CYANIDE AMENABILITY

leaching time, particle size and cyanide concentration) on gold cyanidation process 

evaluate the influence of particle size, cyanide concentration and leaching time on the cyanidation

The mineralogy of the gold ore dictates the required fineness of grinding for adequate gold liberation and the economically optimum extraction recovery.

gold ores are highly amenable to gold cyanidation
