How is Silver Refined?
While this is technically not a part of the refining process, it is a vital step for processing ore and concentrates. Roasting is like calcination but involves heating ore in the presence of excess oxygen. The ore is heated below its melting point and treats the ore with scorching air. Cupellation aims to separate base metals from noble metals.
