  12. cobalt but also manganese as well (Zhang and Cheng, 2007). Each type of a manganese deposit is a problem by itself in the matter of selection of a proper method of concentration, depending on the manganese minerals and their gangue constituents. Beneficiation technology as applied to manganese ores is similar to that for iron ores.

  13. Although manganese is an essential nutrient, exposure to high levels via inhalation or ingestion may cause some adverse health effects. It has been suggested that these adverse health effects, especially neurologic effects, are occurring on a "continuum of …dysfunction" that is dose-related (Mergler et al. 1999). In other words, mild or ...
