Roasting (metallurgy) - Wikipedia

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

This invention relates to an improved method for the treatment of ores to enhance the recovery of metals by hydrometallurgical processes and, in particular, to the recovery of silver from manganese-silver ores by reduction roasting followed by cyanide leaching.

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.
