Sumitomo Corp. to Form Venture With Kazatomprom, Nikkei Says

By Fergus Maguire
Aug. 12 (Bloomberg) — Sumitomo Corp. will form a venture this year with Kazatomprom, the Kazakhstan government-owned nuclear power company, to produce rare-earth metals, Nikkei English News said, without citing anyone.

Annual output is expected to reach 3,000 tons in 2010, the report said. Sumitomo is seeking to increase its supply of the metals used in hybrid and other environmentally friendly vehicles, the report said.

Separately, Toyota Motor Corp.’s Toyota Tsusho unit plans to spend 40 billion yen ($417 milllion) to develop resource supplies, mainly rare earths, over the next five years, the report said.

There is one story here but it is of two different time frames for producing new supplies of the critical rare earth metals needed by Japanese industry to ensure that:

  1. In the near term, it can continue to make (high temperature operation) permanent magnets for electric motors for green applications, and
  2. In the long term, it can continue to make nickel metal hydride batteries for the Japanese OEM automotive industry.

1There is only one way at all that Kazakhstan, without an existing producing or ready-to-produce rare earth mine, could conceivably produce, within a year, rare earths at a 3,000 metric tons (t) per annum rate. That would be if Sumitomo were going to extract rare earths from the tailings (residues) from uranium mining in which rare earths and thorium are almost always found. I suspect that Sumitomo has already developed a process to extract rare earths from the possibly immense tailings, which began to accumulate in the Soviet era when Kazakhstan was the Soviet bloc’s main supplier of uranium. It may also be true that Kazatomprom has already constructed such a plant but didn’t have either or both an efficient technology and the capital to put the plant into operation. Sumitomo is a supplier to, among others, Toyota, and it wouldn’t surprise me if some of Toyota’s 40 billion Yen for rare earths has been used to buy an off-take of selected rare earth metals from this project..

I do not know how a rare earth refinery with a 3,000 t per year throughput could be built and in operation within a year, so either it already exists or a deal has been made with China!

2With a long term view Toyota Tsusho has already announced it will particiapte in the funding of the development of the very large Dong Po rare earth deposit in Viet Nam, but this development will easily take 3-7 years to bring a new mine into production, develop an extraction metallurgy, and build a refinery to separate and purify the metals.

Japanese gologists have lately been looking to confirm rare earth and other mineral deposits in Canada. Could something be brewing along the lines of what’s happening in Kazakhstan and Viet Nam in our northern mineral rich neighbor?
