Jul 13, 2016· GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

The production practice shows that the native gold and many heavy metal sulfide belong to the floating minerals,it's easy to be collected by Xanthate Flotation Collectors. However, due to the content of gold and other factors, the flotation of native gold has the following characteristics.

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 ...Cited by: 55
This complete process plant is for recovering gold by gravity concentration and froth flotation. This commonly applies, but is not to, ore deposits containing GRG gold and sulphide minerals rich in gold . This process will also recover silver associated with sulphide minerals. This simple metallurgical concentrator includes single stage crushing, conveying ...
