Environmental Risks of Mining

In situ leach (ISL) mining. ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012). There is no ore dust or direct ore exposure to the environment and a lower consumption ...

Gold and Silver Leaching by Cyanidation

The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890. From there it spread to Australia, Mexico and the ...

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 ...

Vat Leaching of Finely Crushed Gold Ore

Thus, maximum leaching strength first comes in contact with minimum metal concentration in the ore, and as its leaching potential diminishes, it comes in contact with increasing metal concentration in the ores. In the event of the leach solution entering the vat at the bottom and overflowing at the top, the system is known as upward percolation.
