Metal Extraction Concepts Chemistry Tutorial

A metal ore is a mixture of minerals containing the metal, and other materials in the rock, from which it is economically viable to extract the metal. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Most metal ores occur as a metal oxide, a metal sulfide or a metal
