gravity concentration of gold from base metal flotation millsINTRODUCTION. Gold, because of low head grade and recovery, is usually of minor importance in the economics of poly-metallic base metal ores. TABLE 1 presents gold heads and recovery for some of. Noranda's base metal mills. It should be noted that the stated recoveries are to payable concentrates, but does not.Optimisation of gold recovery by selective gold flotation for copper .Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.

Gold extraction - Wikipedia

However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smelted to form gold bars. In other cases, particularly when the gold is present in the ore as fine particles or is not.
