Low-grade nickel (less than 1.5 wt.%) laterite ores represent about 70% of global reserves but account for only 40% of nickel production. Increasing demand for nickel in recent years has created the need to process such ores. Atmospheric acid leaching of these ores presents difficulties due to the presence of high-acid-consuming serpentinized and clay minerals, leading to pulp gelation and poor mixing, and...

Researchers at the U.S. Dept. of Energy’s (DOE) Ames Laboratory (Ames, Iowa; www.ameslab.gov) led by Ryan Ott have developed a process for recovering rare-earth (RE) metals from magnet scraps. The process involves first crushing neodymium-iron-boron magnet scraps and placing the pieces in a stainless steel crucible, to which chunks of magnesium metal are added. The apparatus is heated in a...

China produces about 98% of the world’s electrolytic manganese metal (EMM), a vital ingredient used in specialty steels, aluminum and electronics. In contrast, the U.S. produces no EMM, says Nick Weir, an executive with U.S. American Manganese Inc. (AMY; White Rock, B.C., Canada; www.american manganeseinc.com). AMY plans to change that by using a patented hydrometallurgical process to extract the...
