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). For gold ores that are amenable to gravity separation, recovery of the coarse,

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore ...

In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
