Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, low-grade copper sulfide overburden, and other copper-containing materials are stacked into a heap.
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.

Copper and Copper Alloys; Applications; ... Crushed ore is carefully dumped into a leakproof lined valley created in an open pit mine.
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution.
Electrowinning can be used to extract the copper from these copper oxide ores. The process for extracting copper from copper oxide ores can be summarized as: Mining : digging or blasting to obtain the ore from the surrounding rock.
