How Is Gold Processed? Reference
The cyanide dissolves the gold without acting on the other rock and metal components of the ore The liquid containing the dissolved gold is drawn off and treated again to release the gold in preparation for refinement At the smelter, the gold is combined with flux and heated to 1,600 degrees Celsius to free it from any impuriti...

Gold cyanidation
Gold cyanidation also known as the cyanide process or the MacArthur-Forrest process is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complexIt is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents ....
Extraction of Gold
Bromine acts more energetically than chlorine, and has also been employed in the extraction The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine Cyanide-process The extraction of gold by the cyanide-method is of great technical importance...
Activated Carbon in Gold Cyanidation

Cyanide Leaching Of Gold
Generally, the finer the gold, the quicker it will dissolve A 45 micron particle of gold would dissolve in 10-13 hours, while a 150 micron particle might take from 20 to 44 hours to dissolve in the same solution Oxygen plays an important role in the leaching of gold in a cyanide solution, also...
Solubility of Gold
Gold is also dissolved by liquids containing chlorine and bromine, but the action is much slower than that of aqua regia and subject to the same difficulties if silver is present heat assists the dissolution Iodine only dissolves gold if it is nascent, or if heated with gold and water in a sealed tube to 50 176...
