Japan's Sumitomo Corp to inject 30 bln yen into SAfrican mining firm

Japanese trading house Sumitomo Corp. plans to invest an additional 30 billion yen ($278.3 million) in South African mining company Assmang Ltd. to bolster its ability to supply steel raw materials to Japan and other Asian nations, the Nikkei reported on Wednesday without citing sources.

The investment will be made via Oresteel Investment Ltd., which owns Assmang.

In January, Sumitomo acquired a 20 percent stake in Oresteel and has since raised it to 29 percent.

By raising it again, to 49 percent this month, its effective interest in Assmang will rise from 8 percent to 13 percent, the report said.

The trading house's total investment in Oresteel will total 45 billion yen, one of the largest outlays in South Africa by a Japanese firm.

Assmang has several mines, with annual output of 6 million tons of iron ore, 3 million tons of manganese and 1 million tons of chrome.

Washington magnesium smelter restart comes closer to reality with better market conditions

What has been cited as the due diligence process, Alcoa Incorporated (Pittsburgh, Pennsylvania) is visiting the possibility of reopening its Addy, Washington, magnesium smelter.

The smelter was idled in 2001 because of raw material costs, the cost of primary magnesium and the high cost of power, as well as a weak market.

The plant produced approximately 30,000 tons per year of magnesium, with the capacity of 45,000 tons per year.

That total is expected to be reached when -- and if -- the plant is restarted.

Yunhai Metals to commission magnesium alloy facility in 2008

Interfax China reported that Shenzhen listed Nanjing Yunhai Special Metals Company Limited plans to commission a 50,000 tonne magnesium alloy facility through its wholly owned subsidiary Wutai Yunhai in Shanxi Province this year.

The report added that Wutai Yunhai kicked off trial production at the facility's 10,000 tonnes magnesium alloy line last month which will be joined by two additional 10,000 tonne lines in September.

Wutai Yunhai's initial 30,000 tonne magnesium alloy facility, along with a 3,000 tonne strontium facility, required total investment of CNY 257 million and have been financed with funds raised through Yunhai Metals' IPO completed last November. In addition, Wutai Yunhai also plans to commence trial production at a further two self-financed 10,000 ton magnesium alloy lines at the facility in October, which requires investment of CNY 189.17 million.

Yunhai Metals estimated that Wutai Yunhai's 50,000 tonnes facility will produce 10,000 tons of magnesium alloys this year. The company produced approximately 80,000 tonnes of magnesium alloys last year and generated operating revenue of CNY 1.65 billion.

Wutai Yunhai produces magnesium alloy from magnesium limestone, and the company currently owns the mining rights to a magnesium limestone deposit with an annual capacity of 108,000 tonnes.

Upgrades improve mineral production

AUSTRALIAN Zircon has reached a milestone in its Mindarie mineral production operation after spending two months improving the mechanics of its plant.

On 18 June 2008, the company dispatched its first full trainload of zircon and titanium minerals for export. Previously, the operation had only been able to dispatch partial trainloads.

According to the plant operator, it managed to significantly improve its mineral recovery processes because of a rampup in productivity.

The plant staff are said to have adapted to the improved operational techniques at the plant, and the facility had undergone mechanical improvements over two months.

The upgrades were required after the company encountered oversized ore feed. It claims the production facilities are now able to handle the oversized ore feed. It also expects growing production levels as further improvements to the facilities are made.

Toshiba in metals deal with Kazakhstan

Japan`s Toshiba Corp has agreed to expand its partnership with Kazakh state-owned company Kazatomprom to include rare metals and reactor components, in the latest move by a Japanese firm to secure raw materials in exchange for technical expertise.

The two sides will continue talks on how they can work together, and the result could be a capital tie-up, said a Toshiba official who asked not to be named. "We are not excluding any possibility," he said. "Kazakhstan has the resources. We have the knowledge on how to use those resources."

Rising raw material prices are prompting Japanese firms to seek strategic allies in resource-rich countries.

Kazatomprom holds 10% of Toshiba`s US-based Westinghouse nuclear power unit, and the agreement would follow a move by Toshiba last year to buy uranium rights to the Kharassan mine in southern Kazakhstan.

Japanese firms, heavily dependent on China for rare metals, have been wary of China`s moves earlier this year to raise export taxes on minor metals such as manganese, silicon and tantalum. Rare metals, such as beryllium, tantalum and hafnium, are used in products ranging from electronics devices to control rods in nuclear plants.

Securing a stable supply of such raw materials is essential for a company such as Toshiba, whose pillars of growth include semiconductors and its nuclear power business. – Mining Journal

Indium eyes upside as LCD demand explodes

Most people could list a host of reasons why prices of computers, televisions and mobile phones are rising, but few would be able to pinpoint indium.

Having languished below $500 a kg for the first four months of the year, indium prices jumped more than 60 percent to $700 a kg at the start of June.

Prices have since slipped to about $650 a kg, but are expected to head higher and the chances of the silvery-white metal revisiting records above $1,000, possibly before the end of the year, are now much higher. Behind the rise are accelerating demand from the electronics industry for liquid crystal display and flat screens, stagnant supplies, the threat of strategic stockpiling in China and investment demand.

"There just isn't enough material to feed what is really quite a voracious LCD machine, which needs ever larger amounts of indium," said Douglas Hunter, a director at UK-based minor metals trading firm Wogen Resources.

"The flat panel industry is increasing production at 25 to 35 percent per annum."

A thin uniform film of indium-tin oxide on glass creates a unique optically transparent electrical conductor for LCDs.

To illustrate demand growth for LCDs, particularly in Asia ahead of the Beijing Olympics, is Korea's Samsung Electronics which is planning to invest 2.74 trillion won in a new LCD line with Japan's Sony.

Other examples include US-based Corning, the world's largest maker of glass for LCD screens, which recently said demand for LCD televisions and computer monitors had been unhurt by economic slowdown in the United States.

Research firm DisplaySearch in April forecast world sales of flat panels would jump by 21 percent in 2008 to reach $123 billion.

Traders say stockpiling by Chinese government to the tune of about 200 tonnes over coming months will trigger price gains.

Indium is a very small part of the cost--less than $3 for a large glass panel. The market at the moment is estimated to be balanced at around 1,300 tonnes.

"We'll eventually see a deficit, prices could head back towards the $1,000 level," said Brian O'Neill, indium materials manager at American Iron and Metal. "The underlying fundamentals are very strong. There is not enough primary production."

About 600 tonnes of total production is primary production, with the remainder coming from recycling.

Electronics applications are said to account for about 80 percent of demand and growing fast is the use of indium in the production of solar panels, which if sustained, would boost consumption significantly.

Simon Gardner-Bond, an analyst at Ocean Equities said the trend towards solar energy will not be slowed by weak global economic growth. "The more affluent consumers will still have the means to buy solar panels."

"You can quite confidently say indium supply is constrained, physically it cannot be ramped up," he said.

"There really isn't the capacity to produce enough indium, as it is a byproduct of zinc mining. Even a large increase in the indium price is not justification enough for most producers to ramp up zinc output just to produce more indium."

Expectations of zinc surpluses and lower prices on the London Metal Exchange at $1,950 a tonne, less than half the levels seen in 2006, are expected to curb indium output.

A problem for supplies is China, the largest producer of primary indium, where export taxes of 15 percent, quotas and previously low prices meant many producers gave up production.

Some Japanese electronics companies eyeing their dwindling stocks are now in China trying to negotiate new contracts for long-term supplies, with little success because they are offering prices below the market, traders say.

The potential launch of a new fund, SMG Indium Resources, which has applied to the US Securities and Exchange Commission for a listing in the United States, could also hit supplies.

SMG said in its prospectus that the company was formed to buy and stockpile indium.

"Our strategy is to achieve long-term appreciation in the value of our indium stockpile," the company said. – Inquirer.net

Some crude bismuth smelters raise quotations

20 Jun 08 – Some crude bismuth smelters raise their quotations this week, because they have received more inquiries recently, close sources reported.
A South China-based smelter with a monthly production capacity of around 30 tons concluded a seven-ton deal of bismuth 99.99%min at RMB155,000/t (USD10.22/lb) early this week, down from the last deal of RMB158,000/t (USD10.42/lb) last week. "It is difficult to make profits at present, because some crude bismuth smelters raised their quotations for bismuth 95%min to RMB128,000/t (USD8.37-8.44/lb) VAT excluded, up from RMB126,000/t (USD8.31/lb) VAT excluded," said the source.
Another South China-based trader with a monthly production capacity of around 40 tons concluded less than ten tons of bismuth 99.99%min at RMB158,000-160,000/t (USD10.42-10.55/lb) in the past two weeks.The source confirmed that some crude bismuth smelters raised their quotations for bismuth 95%min to RMB128,000-130,000/t (USD8.37-8.57/lb) VAT excluded this week, up from RMB125,000-126,000/t (USD8.24-8.31/lb) VAT excluded last week. "The reason is that export market becomes slightly active since the end of May and the beginning of June and crude bismuth smelters received more inquiries recently than in May," explained the source, adding, "However, the demand from domestic market remains weak."

Manganese market in low demand

20 Jun 08 - Manganese market is stagnant with most major buyers out of the market. Sources reported to Asian Metal that demand has been weak in both domestic and export markets. The manganese price falls to around RMB21,200/t (USD3,081/t) ex works and some suppliers are even underselling their stocks at lower prices.
A Hunan-based smelter who has already cut down one of the two production lines told Asian Metal that they received no inquiry from the downstream consumers. "Actually, manganese smelters have cut down their production due to the weak demand and the tight supply of raw materials, but manganese price keeps falling as few buyers are purchasing now." The source stopped quotation early this week but he claimed some suppliers are eager to empty their stocks and thus might lead to much lower prices than the current RMB21,200-21,400/t (USD3,081-3,110/t) ex works.
The source claimed the huge rainfall in large areas of south China has already resulted in roads blocked and the transportation of manganese ores is influenced. "Some smelters may be lack of raw materials and would cut down production further."
Another Hunan-based smelter who has kept huge stocks at hand halted production for maintenance. "The market is too low for us to continue normal prodution unless there are signed contracts to be fulfilled," said the source who puts current manganese price at RMB21,100-21,300/t (USD3,067-3,096/t) ex works. "We are not surprised if some suppliers lowered their price to below RMB21,000/t (USD3,052/t) ex works," said the source, claiming no buyer is in the market now.
Sources reported to Asian Metal that manganese demand would be lower in the summer days and more smelters would have to cut down production. However, some large players are still expanding their capacities to strengthen their competitive power.

Manganese production decreases

20 Jun 08 - As the market turns dull and the production costs remain high, manganese production has been falling. Sources reported to Asian Metal that the market will be even more stagnant and many smelters are about to halt for maintenance.
Asianmetal(English) http://www.asianmetal.com 1XOB
A Guangxi-based smelter complained the transportation of manganese ore has been blocked by the flood. "However, we are not worried about the production as the market is so quiet that we can hardly conclude any deals," said the source who just maintains one of the two production lines to fulfill the signed contracts and is about to halt after finishing the previous orders.
Asianmetal(English) http://www.asianmetal.com 4PRQ
The source claimed many smelters keep some stocks at hand and they might not release the materials unless the major stainless steel mills start purchasing. "While the stainless steel market also keeps dull in China and the foreign buyers are out of the market, we see no hope for the manganese market to warm up in the coming months."
Asianmetal(English) http://www.asianmetal.com I00M
Another Hunan-based smelter who just closed their production due to the low market, confirmed to Asian Metal that as more materials are stocked in the market, the suppliers are very pessimistic about future business. "Some suppliers are underselling their stocks and they just keep a minimum output," said the source who is about to halt for maintenance.
Asianmetal(English) http://www.asianmetal.com 2K4I
The source claimed export market is also very quiet and suppliers see no hope. "More and more smelters would cut down production just as what the stainless steel mills have done."

Magnesium price may drop further in Russia

Magnesium price may drop further in Russia with the decline of magnesium market in China. Participants reported to Asian Metal that the concluded price of magnesium ingot was around RUB170-175/kg (USD7,190-7,400/t) and suppliers have difficulty selling the material at RUB180/kg (USD7,612/t) for the time being.
A Russian consumer purchased 10t of magnesium ingot at a lower price yesterday with the monthly purchasing volume of around 20-30t of magnesium ingot in the spot market. "The magnesium market is in a state of chaos as we received offers from RUB165/kg (USD6,978/t) to RUB190/kg (USD8,035/t), while few deals are concluded in the market," said the source.
The source said that some traders were active in purchasing early June as they believe the price may go up further. However, consumers are reluctant to purchase, which leads to large stocks in the market. "We think the mainstream price is around RUB170-173/kg (USD7,190-7,316/t). We are unwilling to purchase at RUB180/kg (USD7,612/t) currently," said the source.The source believes the magnesium price may go down in a short time due to adequate supply.
A Russian trader said that few deals are concluded as some consumers stop purchasing to wait for lower prices, unwilling to accept the price of RUB180/kg (USD7,612/t). "We still offer RUB180/kg (USD7,612/t) for magnesium ingot, the same as that of last week. Yet we have not concluded any deals this week," said the source.
Asianmetal(English) http://www.asianmetal.com YMUH
In view of the current market situation, the source plans to lower offers soon.

Magnesium in Europe nudges down

Sliding price of magnesium in Chinese market is affecting price in Europe as sources reported deals concluded at around USD5,800-5,900/t in warehouse Rotterdam because materials bought at high price are still in Europe. According to participants, the dropping price in China could only reflect much in European market when new material arrives in Europe.

Meanwhile, market is extremely quiet with buyers buying only hand to mouth and waiting for the price drop in Chinese market to touch the floor.

Some participants reported getting offers from China as low as around USD5,040/t while most market participants reported quotations at around USD5,400-5,600/t. However, the general feeling in the market is that price will continue to move down until some producers start to close down for Olympics then sellers will have a good reason to ask for high prices.

According to an European dealer who put the price in warehouse Rotterdam at around USD5,800/t, although he has not concluded any deals recently due to weak demand, market is resting and will start to move again if Chinese suppliers reduce their stocks.

Another trader reported some inquiries recently which he will quote at around USD5,800-5,900/t in warehouse Rotterdam as spot deals are at that price, down from around USD6,000-6,100/t they were selling before.

The source agreed that price in Europe will go down gradually because material bought from China now has not arrived in Europe. The source added that there is less material in Europe at the moment since buyers are not buying because of the high price and if anybody wants to buy material now, he should pay what suppliers quote.

But the fact is that buyers are watching the market as price in China is going down and most of them expect it to hit below USD5,000/t FOB.

Magnesium producers expecting higher prices

After the magnesium ingot market stopped falling Tuesday, producers expect higher prices in the following week. Some of them have started to raise offers to test the market, sources reported to Asian Metal.
A Shanxi-based producer is fully running at its capacity of 5,000tpy with around 40t of magnesium ingot in stock. "We lifted our offer to RMB32,500/t ex works today from RMB31,500/t (USD4,578/t) ex works late last week, but no deal has been concluded at the increased price," said the source. "Consumers need time to accept the price rebound."
The source confirmed that the price dropped drastically last week when some small smelters undersold materials at around RMB30,000/t ex works or lower prices. "In fact, we also sold small quantities of magnesium ingot at around RMB30,500-31,000/t (USD4,433-4,506/t) ex works," said the source. However, after the price plummeted from a level above RMB36,000/t (USD5,233/t) ex works to around RMB31,000-32,000/t (USD4,506-4,651/t) ex works late last week, most smelters would not like to lower prices further.
Asianmetal(English) http://www.asianmetal.com 6BSY
The source revealed that they have received more inquiries since Wednesday, mirroring that the market demand is warming up. Therefore, the source predicts that the market will rise slightly in the following week.
Another Shanxi-based producer reported that the market trend is still unclear. "To be exact, the market stopped decreasing rather than rebounded," said the source. The source confirmed that some smelters have begun increasing offers since Wednesday, but the market still sees few deals concluded as consumers refuse to accept the increased prices. Meanwhile, the export market remains sluggish, which will not encourage the domestic price increase.
Nevertheless, the source thinks that the price is likely to keep stable or rise slightly in the near future given the fact that small smelters who have sold most of their stocks in the past two weeks will not have many materials to be released in the spot market, and large smelters are still insisting on high prices above RMB33,000/t (USD4,797/t) ex works. Furthermore, some smelters which do not comply with the environmental standard will be shut down soon before the Olympic Games.
The smelter is running at its capacity of 1,500tpm and most of the products are exported. It is still fulfilling contracts signed at USD5,800-6,100/t FOB without any new deals concluded recently. According to the source, many exporters put their offers at USD5,400-5,500/t FOB, though the export market keeps quiet.

Global polymer providers announced product prices increase

Various raw material providers in the polymer business have announced their decisions to increase product prices starting from this June or July.

As of June 1 this year, BASF will raise its gross market price (GMP) for Polystyrene by 100 euros per metric ton. BASF claimed that the prices of styrene had reached a historical high in the past week, saying a further price increase may be possible.

To response to the surge of energy cost, Dow Chemical also announced last week the rise of all its products by up to 20% – depending on their exposure to rising energy, feedstock and transportation costs – and will review all terms to all customers.

Rhodia Polyamide and Solutia, two global nylon providers, have also announced that they will increase the prices of some of their polyamide products starting from July 1.

Rhodia Polyamide decided to increase the price of its PA 6.6 Stabamid Polymer range in Europe by 200 euros/MT, effective from July 1 – or as contracts allow – in order to offset rising raw material, transport and energy costs.

Solutia, as announced on June 4, also increased prices by 10% across its Ascend and Vydyne (PA66) resins worldwide. The increase applies to orders shipped on or after July 1 and will be applied across the Ascend and Vydyne product families.

Magnesium price moves down in China

Magnesium ingot market slowed down late last week when more traders and consumers stood on sidelines without purchasing. Participants anticipate lower prices of magnesium ingot in the first half of June.

A Shanxi-based smelter, running with an output of 400tpm, reported that the magnesium market became stagnant late last week when consumers refused to accept high offers of RMB36,800-37,000/t (USD5,295-5,324/t) ex works and smelters would not like to lower offers.

"We sold small quantities of magnesium ingot at prices slightly above RMB36,500/t (USD5,252/t) ex works early last week, but failed to conclude deals at higher prices later," said the source. "Except that end users still purchased from hand to month to maintain production, most traders ceased buying due to the dull export market."

The source reported that some smelters in the region have lowered offers to RMB36,300-36,500/t (USD5,223-5,252/t) ex works to attract buyers. "But we won't reduce our quotations sharply as most of our output before June 8 has been ordered," stated the source. However, the source is not so optimistic about the market in June, fearing that the whole market may be dragged down fast by some small smelters who would cut down offers to promote sales in order to collect money quickly to pay the increasing prices of raw materials.

"We have started to receive unsolicited offers of magnesium ingot since Thursday, mirroring the market slowdown," a trader source reported to Asian Metal last Friday. "However, we'd prefer to hold back from buying at the quoted prices of RMB36,400-36,500/t (USD5,237-5,252/t) ex works as we firmly believe that the market may go down sharply."

1.4 Emission from Products in Service

1.1 Flame retardants

Flame retardants are added to polymeric materials, both natural and synthetic, to enhance the flame-retardancy properties of the polymers.

There are four main families of flame-retardant chemicals:

Inorganic flame retardants including aluminium trioxide, magnesium hydroxide, ammonium polyphosphate and red phosphorus. This group represents about 50% by volume of the global flame retardant production /9/.
Halogenated flame retardants, primarily based on chlorine and bromine. The brominated flame retardants are included in this group. This group represents about 25% by volume of the global production /9/.
Organophosphorus flame retardants are primarily phosphate esters and represent about 20% by volume of the global production /9/. Organophosphorus flame retardants may contain bromine or chloride.
Nitrogen-based organic flame retardants are used for a limited number of polymers.

Global production figures and trends in consumption are discussed further in section 1.3.

About 350 different substances used as flame retardants are described in the literature. The index of Flame Retardant /13/, an international guide to more than 1000 products by trade name, chemical, application, and manufacturer, contains more than 200 chemicals used in commercial flame retardants. A comprehensive list of flame retardants is compiled by the Swedish National Chemical Inspectorate /14/.
