    Stage 3 Hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little complex for gold ores in particular, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation characteristics.

    The gold is not sufficiently liberated as is the case with placer ores, and therefore crushing and grinding is required to allow the cyanide to access gold components. Permeability is the major indicator of how much communition is required prior to leaching.

  • 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 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.

  • Why Gold Mines Are Adopting Hpgrs To
