The isolation of copper metal from leach liquor is a two-step process (Wikipedia: Copper Extraction Techniques ). The leach liquor obtained after heap irrigation has a very low concentration of copper dissolved into it, around 0.5 - 2.0 g/L.
Copper extraction techniques refers to the methods for obtaining copper from its ores. This conversion consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Mining is the process of digging things out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron. Mining can also include other things like oil and natural gas.

Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper.
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.
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.
This article is a little unwieldy and far-reaching to my mind. Copper extraction obviously involves a lot of things related to many wide and varied subjects, a lot of which actually have nothing to do with the extraction per se, of copper. This, sadly includes; All of the geology and formation of copper orebodies

Copper minerals generally occur as oxides or sulfides. Copper sulfides are crushed, ground, floated and the resultant concentrates are transported to smelters for refining into anodes. Today most copper oxides are liberated by solvent extraction. Ore is exposed to acid in a heap leach to liberate the copper ions.
