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.
It is not used much anymore, because most leaching is heap leaching, carried out in the outdoors, where drip emitters or sprays distribute the cyanide solution to a large structure of gold ore, called a "heap". And while the pile of ore is called a heap, it is not a haphazard pile of rocks.
How to Leach Gold Ore With Chlorination ... The use of chlorine is both the cheapest and most plentiful method for leaching gold. When you mix sodium chloride and hydrochloric acid together, you produce a form of electrolysis that removes gold from rock and soil.
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH
CSIRO, Australia, has developed a thiosulfatebased reagent system for gold leaching that has excellent stability and shown broad applicability in the laboratory compared to the thiosulfate system commercially implemented by Barrick to treat double refractory gold ore following pressure oxidation at its Goldstrike Mine in Nevada, USA.
I visited a plant in Malaysia (Penjom) where this was such a serious problem that they had to use kerosene to foul (blank) the organic carbon prior to cyanide leaching. They used a resin in pulp system then for the recovery of gold which worked very efficiently such that they were able to profitably treat the ore and recover the gold.

The O product series shares the same leaching process and flowsheet as cyanidation. Ecogoldex O product series can replace cyanide in gold ore mine flowsheet (Heap leach, CIL/CIP) seamlessly without any circut change or equipment modification. The E series stripping/recovery process is as simple as step 1,2,3. This process can be described as:
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
"Increased Recovery from PregRobbing Gold Ore at Penjom Gold Mine" • The carbon was not as active in the coarse highgrade gravity concentrates; regrinding the concentrates increases the activity of the carbon in the ore and reduces leach recovery. • A relatively highgrade concentrate (100200 ppm Au)
