(1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Mining as an industry underwent dramatic changes in medieval Europe.The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron.Other precious metals were also used, mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than through deep mine shafts.

Usually chalcopyrite, sphalerite and iron sulphides are present with this type of ore. Gangue minerals are typically various silicates, carbonates, and often talc the latter which presents flotation challenges. The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process.

At Corinth, Vermont, the Pike Hills Mines Co. is employing the Wetherill-Rowand separator in separating pyrrhotite and chalcopyrite from gangue and from each other. The ore carries pyrrhotite and chalcopyrite in a quartz and mica schist gangue; the run of mine ore is cobbed to run 3 per cent. copper before going to the mill.

ore is hoisted to the surface for further concentration. In the mine, workers try to separate the ore-bearing minerals from the barren rock as much as possible during the mining process. In some mining districts, the lead or zinc is found in massive deposits and mined similar to coal using room and pillar methods.

Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite
