  • The Metallurgy of Cyanide Gold Leaching An Introduction

    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.

    1. Introduction. Cyanidation is the method applied for recovery of gold from ores for a century. New cyanidation processes based on the recovery by adsorption to activated carbon of leach solutions containing low grade (concentration) gold have been developed since 1970s and 85% of gold recovery is accomplished with this technique today (G246;nen, 1992, Hendrix, 1994, 214;rg252;l and Atalay, 2002).
