The Metallurgy of Cyanide Gold LeachingAn Introduction

 · 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 exposedi.e. the gold is liberated.
