Copper has six major life cycle phases: mining, smelting and refining, semi-fabrication, product manufacture, use phase and recycling. Recycling takes place both at smelters for copper production and at fabricators for production of semi-finished products. The International Copper Association’s Copper Cathode Life Cycle

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated(concentrated)…

Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
