What is Gold Cyanidation? (with picture)

Jul 07, 2020· Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

Cyanide Bottle Roll Test | Mining | SGS

A cyanide bottle roll test is the industry standard first step in assessing the gold recovery possible by cyanide leaching. During a bottle roll test, prepared ore is gently agitated in a cyanide lixiviant or leaching solution. Oxygen levels, alkalinity, acid consumption and other parameters are monitored and strictly controlled throughout the ...
