At present leaching of goldcontaining raw materials by cyanide is the main hydrometallurgical process and the main advantage of cyanide is high selectivity with regard to gold. However, leaching by cyanide solutions has a set of substantial drawbacks: process duration, high cost of the reagent, nonadaptability of "stubborn" ores and concentrates, absence of possible regeneration of cyanide solutions and the .

Cyanide. Yet another gold removal process is ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a foam. The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles.

Cyanide Leaching. It is an extremely versatile method. It can be successfully used as a means to assay in 1 quart fruit jars, in smallbatch production such as extraction of a few tons of good ore or concentrates in a small cement mixer, or in megaton heapleaching operations. It is a relatively simple process.

Cyanide. In the late 1800s, cyanide started to be used to concentrate and capture gold from ore in a similar process to the mercury extraction, but is more efficient and loses less gold to the tailings. Once the rock is pulverized, it is mixed with water to create a slurry and a cyanide solution is added.
