In situ leach - Wikipedia
In-situ leaching ISL also called in-situ recovery ISR or solution mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state.
Recovery of Copper by Solution Mining Methods
Solution mining repli es the natural process of oxidation and reduction described above. Dilute acidic solutions are introduced to the copper-bearing ores causing dissolution of soluble copper minerals Table 1 remaining in the leached cap and underlying enrichment blanket.
Copper extraction - Wikipedia
The copper sulfate solution the pregnant leach solution is then stripped of copper via a solvent extraction and electrowinning SX-EW plant with the barred denuded sulfuric acid recycled back on to the heaps.
The earliest evidence of cold-hammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia which dates between 7200 to 6600 BCE… Concentration · Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining… Froth flotation · The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. Copper… Hydrometallurgical extraction · Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching. These ores are a mixture of copper carbonate sulfate…
Copper ore divides into ore sulfide ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation for refractory mixed copper ore and refractory oxide ore normally use hydrometallurgy process .It is a high technological enterprise that integrated research manufacture sales and service . The company has multiple subsidiaries such as Mineral
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.
Innovations: Introduction to Copper: Mining and Extraction
The oxidized ores consisting of the sili es carbonates and sulfates are treated by several methods all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Copper Mining and Production Processes Explained
Leaching offers an alternative to copper mining. First the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis.
