Manganese Silver Ore

Effect of Manganese on Silver Leaching

in the case of manganese ores it commonly happens that the ore in the upper levels is more refractory than that in the lower, though containing the same percentage of manganese. An oxidizing roast applied to any silver ore usually renders the bulk of the silver insoluble in cyanide.

Manganese Silver Ore Treatment Method

Oxidized silver ores containing the higher oxides of manganese are generally refractory to metallurgical treatment. Manganese fouls mercury if amalgamation of the gold content is attempted. A refractory compound of manganese and silver is formed, probably a manganite, which is insoluble in cyanide solution and other common solvents for silver.
