acids used in mining

Copper: Sulfuric Acid is used for leaching of copper from oxide ore, and some sulfide ores. The leaching solution is claimed to be diluted and recycled. However, it is recycled into lined ponds of high toxic levels of sulfuric acid. The sulfuric acid can enter the soil and groundwater through breaks, spills, tears in liners.

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 ...
