The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 20140183;32;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.

cyanidation process in dressing of ore high production

Gold cyanidation . Gold cyanidation. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides.

However, in situ mining cannot be implemented in all cases as the ore needs to be beneath the water table (the level at which the ground is saturated with water) and it needs to be porous enough to let the leaching solution dissolve (Topf, 2011). Unfortunately, in situ leaching can also be very harmful if the solution leaks into the water supply.
