Metallurgy: Extraction of metals from below

METALLURGY Extraction of metals from below the surface of the earth forms a major industrial endeavor. Since most metals are reactive, most of them are not found as free elements under the earth’s surface. Relatively unreactive metals like silver (Ag), gold (Au), Platinum (Pt) are found as pure elements. Copper (Cu) is found in free state as well as in combined state. Naturally occurring materials or compounds which are a combination of metals with other elements are called minerals ... Learn what metallurgy is and how it is used to extract metals from ores.
