9 Ore Deposits and Economic Minerals – Mineralogy

9.1.3 Mineral Deposits, Ore Deposits, and Mining. A mineral deposit is a place in Earth''s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse ...

The hydrometallurgy is a main method of gold extraction. The leaching process as an important part of hydrometallurgy can be classified into three species depending on the different leaching conditions: under acid phase (pH < 3) with chlorine, thiourea [], ferric chloride, and thiocyanate []; under neutral phase (pH within 5–9) with halogens [] and thiosulfate []; and under the alkaline ...

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using 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 ...
