When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire assay, which leaves a matrix free button of the metal. This button is then dissolved in the appropriate
Mining. The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open pit 90% of ore is mined using the open pit method.

Copper Mining Extraction Process Flow Chart. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining stages required for sulfide ores.
Most of the copper used before 4000 b.c. came from the random discovery of isolated outcroppings of native copper or from meteorites that had impacted Earth.
