Gold extraction

A quot;refractoryquot; gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold.

Grinding media quality assurance for the comminution of

GRINDING MEDIA QUALITY ASSURANCE FOR THE COMMINUTION OF GOLD ORES 27 Introduction One of the basic operations in minerals processing is grinding of the ore to the point where valuable minerals are liberated from the host rock. Subsequent operations then separate the desirable minerals from the gangue or waste.

Arrastras. Historic Gold Mining Method for Processing Ore

It generally took several hours to grind the ore sufficiently for further processing. When it got ground down to near completion, an appropriate amount of quicksilver was added with the fine gold that had been released. The grinding process would continue, allowing the mercury and gold to amalgamate.
