Fines are just fine for this direct-reduced-iron process

Article Abstract:

BHP Iron Ore in Port Hedland, Australia, is commercializing a new a new direct reduced iron (DRI) process called the Finmet, which was developed by FIOR de Venezuela of Puerto Ordaz, Venezuela and Voest-Alpine Industrieanlagenbau GmbH of Linz, Austria. BHP is constructing a 2.2-million-mt-per-year iron ore facility, which is scheduled to operate by about the end of 1998 using the Finmet process. The Finmet process could deem produce iron ores that are finer increasing product value. Meanwhile, BHP plans to build another plant to use the Finmet process that is set to operate in 1999 in Puerto Ordaz.

Bugs do the work in asymmetric synthesis of amino acids

Article Abstract:

NSC Technologies of Mount Prospect, IL, has developed two new amino acid intermediates, d-tyrosine and d-phenylalanine, through the symmetric synthesis process. In the asymmetric synthesis process, d-transaminase is utilized which will be reacted with enzyme-producing microorganisms, an amino donor, and a keto-acid substrate in order to create the desired amino acid. The process also creates a byproduct, acetolactate, which can be easily converted into acetoin. A single batch of the said ingredients can produce a ton of the derived amino acids.

A golden streak for these poison-eating bugs

Article Abstract:

A biological process for decomposing toxic thiocyanate has been discovered by researchers at CSIRO and BacTech Pty. Ltd., both based in Perth, Australia. Thiocyanate is a waste produced when gold is extracted from an ore using cyanide. Peter Franzmann, a CSIRO researcher, said the microbes are effective over a wide temperature range of between 15 and 37 degrees Celsius and can survive thiocyanate levels of 7,000 ppm, salinities of 100 grams per liter and arsenic contaminations.
