Water Consumption at Copper Mines in Arizona

Hydrometallurgical (Leaching) Process Leaching, solvent extraction (SX) and electro-winning (EW) have been used for producing copper from oxide ores since the 1960s and since the 1980s some secondary sulfide ores, such as chalcocite, can also be treated in this manner. Figure 1 shows one possible flowsheet for the leaching process.

Leaching Mining Fundamentals

Leaching Mining Fundamentals. Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out

Innovations in Copper: Mining & Extraction: Producing

The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vitriol solution a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
