Gold Cyanidation ProcessMineral Processing & Metallurgy

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.


Gold Cyanidation ProcessMineral Processing & Metallurgy

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.

The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 2014· Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.
