Gold Cyanidation Wikipedia Gold cyanidation is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex.
Heap leaching is the process to extract precious metals like gold, silver, copper and uranium from their ore by placing them on a pad (a base) in a heap and sprinkling a leaching solvent, such as cyanide or acids, over the heap.
INDUSTRY STATUS The mining industry first became interested in the Bureau of Mines' developments in gold/silver heap leaching technology in the late 1960's, and the first'commercial cyanide heap leaching process was used at the Carlin — 'A" Gold .
Costeffective heap leaching offers a number of advantages, including: Comminution costs are reduced as the ore is only crushed, not ground. The cyanide solution is recycled through the heap, reducing the amount of cyanide used in the operation. The process is especially suitable for lower grade ores and ore with a high clay content. Gold Recovery
This improves the amount of gold that can be recovered by further processing using equipment such as the InLine Leach Reactor. All gold concentrates produced by the InLine Pressure Jig can be intensively leached using the InLine Leach Reactor. For ore bodies less than 350 micron in size, a flotation flowsheet will be recommended.
