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

Flotation Mineral Processing

Flotation Mineral Processing

Flotation is an economical and effective separation of refined gold technology especially for these ores that are not suitable for other processes such as gold-bearing copper ore base metal ore copper-nickel ore platinum group ore etc. Flotation is also used to remove impurities before hydrometallurgical treatment ie carbon pre-flotation to purify low-sulfide and refractory ores for further processing.

Sulphide Gold Ore Treatment By Leaching And Flotation

Sulphide Gold Ore Treatment By Leaching And Flotation

Apr 18 2016 There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown with some variations are probably the most commonly used. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded. Here a Mineral Jig is used in the Ball Mill Classifier circuit. This recovers coarse and fine free gold .

Optimisation Of Gold Recovery By Selective Gold Flotation

Optimisation Of Gold Recovery By Selective Gold Flotation

Abstract 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.

Sulfide ores and pyrites in particular have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances visible gold can not be seen under microscopic examination of pyrite gold ores. However if the ore is ground to -200 mesh most times a few specs of gold can be visibly seen under microscopic .
