Dec 26, 20190183;32;Stateofart cyanidation flow sheet. In the SCE 1 process, cyanidation is conducted for POXtreated gold concentrate. The unit processes are modeled as one unit; however, in a real process, the carboninleach/CIL circuit consists of multiple reactors.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
Whether gold is the primary value metal or part of a suite of metals such as nickel, cobalt, copper, or platinumgroup metals (PGMs), selection of an appropriate combination of these units would likely result in a usable flow sheet.

The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.

With potassiumaurocyanide containing 0.1 per cent., or $603, gold per ton, which had failed to precipitate at all on the bright sheetzinc, the gold was entirely precipitated from the solution in twentyfour hours by filtering it through a very large excess of zincshavings (over four hundred times the weight of the gold present).
The Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated.
