#0183;#32;From Start To Finish: The Mining Life Cycle Mines are humanmade structures, and this basic fact already tells us a lot about the nature of mining as an industry. While the mineral deposits that make mining profitable are already present underground, mining companies still need to prepare the infrastructure necessary to extract and process these resources.
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

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. The processing techniques depend on the nature of
