silver ore manganese


Much of the silver in ores AZ-1, CO-2, and NV-1 (fig. 2 is intimately associated with the manganese mineralization as 43, 40, and 38 pct of the silver (table 3) was coextracted with 78, 82, and 75 pct of the manganese, respectively. An additional 25, 14, and 2 pct of the silver was made accessible to cyanidation by removing manganese.

manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.
