  • Gold Cyanidation Ground Truth Trekking

    Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide quot;vat leachingquot; mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

  • The Metallurgy of Cyanide Gold Leaching An Introduction

    Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

  • Introduction to Cyanide Gold Mining

    Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold.
