Advances in the Cyanidation of Gold ScienceDirect

01/01/2016· In the case of cyanidation plants processing gold ores with metallic sulfides, oxygen is not only used to optimize plant throughput but also to enhance gold extraction. Because the dissolution of sulfide minerals consumes oxygen ( (26.8) , (26.10) , (26.11) ), it is important to avoid a reduction in the gold leaching rate associated with low DO in the pulp.

The Metallurgy of Cyanide Gold Leaching An Introduction

20/10/2014· Cyanidation is used for gold that is distributed finely through a mineral matrix. 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
