FLOTATION of GOLD

Flotation behaviour of gold associated in the plati num group metals is apparently the same as that for the PGMs or other minerals associated with the PGMs . Therefore, the reagent scheme developed for PGMs also recovers gold. Normally, for the Sotation of

Gold Flotation Mineral Processing Metallurgy

Jul 13, 2016· It was describe by the use of 600 series of flotation reagents which were developed primarily for the purpose of depressing carbonaceous and siliceous slimes in the flotation of gold ores. Carbonaceous material not only greatly increases the bulk and moisture content of a flotation concentrate, but its presence makes cyanidation of the concentrate difficult or impossible owing to reprecipitation of the gold

Silver Gold Recovery Flotation Process

Oct 17, 2016· The discharge from the tube mill is first passed through a 4 mesh screen to separate out coarse material, which is laundered direct to the classifier. The remainder of the pulp, diluted to give a W/S ratio of 1/1, passes to a Denver Sub A Flotation Cell, from which 60% of the gold and silver in the feed is removed as a concentrate.

Optimisation of gold recovery by selective gold flotation ...

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. This may be an alternative ...

Gold Extraction Recovery Processes

Flash flotation of free coarse gold using

The particle size has a great effect on the recovery of gold by flotation due to its high density. The flotation is effective for gold particles in the range of 20200 μm. For finer sizes, the selectivity of the gold decrease because of the floating of ore gangue. For thicker particle sizes, flotation must be done

Flotation of Gold and Gold Bearing Ores ScienceDirect

Jan 01, 2016· Some gold flotation pulps may contain humic and tannin substances and sulfide ions from sulfide mineral that are reported to impact on gold flotation.

Recovering Gold through the Froth Flotation Process ...

Feb 06, 2018· Feb 06, 2018· Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a large tank filled with distilled water.
