The gold ore dressing method. Various types of gold ore have different beneficiation methods due to their different properties. However, gravity separation, flotation, amalgamation, cyanidation and recent years' resin slurry method, carbon slurry adsorption method, heap leaching method, etc. are commonly used to extract gold.

Extracting Gold - Extracting gold is a term related to gold. Learn about extracting gold at HowStuffWorks. ... Leaching dissolves the gold out of the ore using a chemical solvent. ... which can be recycled for future processing. Finally, the gold-bearing solution is ready for electrowinning, which recovers the gold from the leaching chemicals.

What I claim is: A method of recovering gold from auriferous saprolite ores which comprises cyaniding a pulp of the ore, treating the cyanided pulp with charcoal which has been preheated to about 1000° C. and subjecting the mixture to a froth flotation 4' process in the presence of a reagent favorable to the flotation of auriferous carbon.

In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns ...
