Cadmium is a soft, bluish-white metal bearing close resemblance to zinc and mercury. Malleable, ductile, and having high resistivity to corrosion, cadmium is used as a protective layer when deposited on other metals. the metal has many industrial uses as well; it is a major component in battery production and is used in electro-plating.

Metallurgical literature has no record of any ore beneficiated for cadmium alone, and the cadmium of commerce is derived from zinc ore, with which cadmium is generally associated. Zinc ores free from cadmium—e.g., the ores of the Franklin and Stirling mines, New Jersey, and of Broken Hill in Rhodesia—are rare. Blende concentrates of 50 to 60 per cent grade have contained (in …
