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
