Gold cyanidation - Wikipedia
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 complex. It is the most commonly used leaching process for gold extraction.

Method of Gold Extraction using Borax -Small …
Borax Method of Gold Extraction. Unfortunately, this method is ineffective in areas using whole-ore amalgamation, since up to 90% of the mercury is lost to the tailings (the waste product consisting of fine sand) and only 10% is lost by blowtorching of amalgam. Thus, only a small fraction of the mercury spill from whole-ore amalgamation can be ...
Cyanide Chemistry & Gold Extraction
In the cyanide-solution, the oxygen and the cyanide of potassium may exist side by side in solution (as experiment shows) without sensible action on each other, unless the presence of gold determines the Elsner reaction at the point where oxygen, water, gold, and cyanide of potassium meet. If a thorough utilization of the cyanide is desired, the action of the oxidizer should be such that the ...

Non Cyanide Leaching INTRODUCTION, ... In any case, CLS will always hold at least 100 times more gold than cyanide, thus allowing much smaller amounts of liquid to be used in any given system for a given amount of ore. Since there are a number of ways to handle any given ore with CLS one should explore each avenue carefully before adopting any particular system. Many ores may require a simple ...
