Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Underground mining (hard rock) Wikipedia
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal
METHOD AND APPARATUS FOR MINING COPPER Ehsani
Mining methods and systems are disclosed for In-Situ Leaching (ISL) of the mineral ores. ISL extraction is conducted by injecting a suitable leach solution into the ore zone below the water table; oxidizing, complexing and mobilizing the minerals; recovering the pregnant (loaded) solutions through production wells (extraction wells or recovery wells); and, finally, pumping the minerals bearing
Recovery of Copper by Solution Mining Techniques AZGS
Copper as well as a number of other commodities are harvested by solution mining methods. Water-soluble salts such as potash (sylvite), rock salt (halite), thenardite (sodium sulfate) and nahcolite (sodium bicarbonate) are commonly derived from massive sedimentary deposits by in-situ methods.
