The Metallurgy of Cyanide Gold Leaching An Introduction

Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2 0.5 181;m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant.

75 Gold Recovery Methods Gold Hydrochloric Acid

The Haber gold process (HGP) is, in many respects, similar to the cyanide method in the recovery of hardrock gold, but acting faster and without raising any significant environmental issues. Both methods rely on chemicallybased gold extraction technology that makes use of a lixiviant (extracting solution) to leach gold into solution from the ore.

Method of Gold Separation 1. Gravity Separation

Gravity separation is an ancient and the most commonly used gold enrichment method. Placer gold is usually showed a single native gold in the form, whose particle size is generally greater than 16 t/m3 having big density contrast with gangue. So the gravity separation is the most important method for placer gold beneficiation.
