The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes. What is Copper Used For? Water Pipes; Wiring; Coins; Electronics; Cookware ...

In open cast mining method, before design is made for the pit, to know the geological conditions is important for the stability of the pit slopes. In open cast, flexibility in production is more since it is not that difficult to use equipment as in underground. Hence higher production can be planned with low cut of value.

Copper processing involves mining copper ore (between 0.6-1% copper) and turning this into sheets of 99.99% pure copper. The process usually begins with an open-pit mine, where rock is drilled and blasted. The resulting boulders are put through primary crushers before hauling equipment transports the ore to a processing site.

Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock or overburden must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, there is additional waste rock that must be separated from the ore.

At regular intervals along the shaft, horizontal openings called drifts are driven toward the ore body. Each of these major working horizons is called a level. The shaft is equipped with elevators (called cages) by which workers, machines, and material enter the mine. Ore is transported to the surface in special conveyances called skips.
