US3906075A - Process for extracting a manganese concentrate .A process for extracting a manganese oxide concentrate of metallic copper, nickel and cobalt from manganese, such as maritime manganese concentrations. The ore is first finely ground and then is leached in an aqueous suspension at temperatures of 90*-100*C. and at a pH value above 3 with sulfur dioxide or sulfurous.Manganese Mining and Processing: Everything you Need to KnowMay 7, 2014 . More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it's transferred to a processing.
