Gold Ore Plant Operation Procedure. Procedure Of Using A Ball Mill For Gold Ore. Procedure of using a ball mill for gold orethe gold ore from the mine site is always with size 0-400mm or 0-600mm after blasting we use the crushing plant to crush the raw gold ore into 0-8 or 0-10mm primary grinding and classifying section the gold ore with the size 0-8mm or 0-10mm will be fed into the ball mill

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

of the individual gold particles in the ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3).
