Minerals | Special Issue : Advances in Mineral Processing

Conventional floatation treatment has poor effects on recovering Cu-Co sulfide-oxidized mixed ores due to the high oxidation rate and large amount of carbonaceous mud of the ores. The research results showed that the pre-removal of carbonaceous mud - asynchronous flotation process got a better flotation results than the conventional process.

Copper Sulfide Flotation - Mineral Processing & Metallurgy

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.
