Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from oreusing a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i

Leaching Mining Fundamentals

Leaching is a chemical process in mining for extracting valuable minerals from the ore. Leaching also takes place in nature where the rocks are dissolved by water. Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained.

Agitation and column leaching studies of oxidised copper

Sep 01, 2017· 2.3. Agitation leaching. Batch agitation leaching tests were performed using a 1 L polypropylene beaker provided with a pH-temperature electrode to determine the maximum solubilisation yield of cobalt and copper and the proportion of trivalent cobalt in the ore.A total of 200 mL of 75 g/L H 2 SO 4 aqueous solution was placed in the beaker and a weighted ore sample (15% (w/v)) was added.
