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
