manganese production method

Utilization of Electrolytic Manganese Residues in

Electrolytic manganese residues (EMR ) are one of industrial by‐products generated during the production of electrolytic manganese metal. To reduce the EMR hazard to environment and invent value‐added materials, porous ceramics were prepared by the pore‐forming method with EMR and various additives.

Drinking Water Health Advisory for Manganese, January 2004.

Manganese is a naturallyoccurring element that can be found ubiquitously in the air, soil, and water. Manganese is also an essential nutrient for humans and animals (Leach and Harris, 1997 U.S. EPA, 2003a). Adverse health effects can be caused by inadequate intake or over exposure (See a review by Keen et al., 1999 and Keen et al., 2000).
