The low concentrations of the zinc sulphide mineral in most zinc ores mean that the ore must first be concentrated before extracting the metal The zinc blende (sphalerite: zinc sulphide)is first crushed to powder and then treated by froth flotation (that process is described in the copper unit It is used in the extraction of several metals)
Silver processing: 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.
