How silver is made material, making, history, used

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zincbearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.

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.

Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock.
