Technik » Gold flotation process

Flotation is one of the most widely used methods for processing gold vein ore in gold processing plants. In most cases, the flotation method is most effective when used to treat gold ore containing sulfide minerals with high recoverability. Because not only can gold be enriched into sulfide mineral concentrates by flotation, but tailings can also be discarded, and beneficiation costs less. Flotation is also used to process polymetallic gold-bearing ores, such as ores such as gold-copper, gold-lead, gold-antimony, gold-copper-lead-zinc-sulfur.

The treatment of polymetallic ore is mostly flotation, but when the ore contains coarse-grained gold, it must be processed by re-selection equipment such as jigging before flotation to avoid causing problems in future selection operations. The loss of gold. Gravity separation equipment such as chute and shaker are also often used to treat flotation tailings and mercury-mixed tailings. Gold can be recovered by sweeping, which is difficult to flotation and difficult to mix with mercury. .
