By Mac Arthur and Forrest's Cyanide process, Silver can be extracted from their ore. This can also be done by leaching and smelting. Step1: For the extraction, ore A g 2 S is crushed into fine particles. Step2: By the Froth Floatation, the concentration of ore is done. Step3: T he concentrated ore is then treated with NaCN.

silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths …
