Sulphide Gold Ore Treatment by Leaching and Flotation Process
Here a Mineral Jig is used in the Ball Mill Classifier circuit. This recovers coarse and fine free gold preventing any build-up in the circuits especially in the grinding circuit. ... This scheme would be used where it is not possible to make a flotation tailing low enough in gold to be discarded but flotation is warranted for one of the ...
How To Make Your Flotation Circuit Twice as Strong
In Flotation, we use a formula to size the circuit we need to chase the recoveries we want. R = 1 – exp(-k.t)... Recovery is regarded as a function of residence time, t.
Coal Flotation
In India, standard coal flotation test is conductedfor developing a strategy for fine coal (−0.5 mm) beneficiation and designing the circuit. Standard flotation tests are performed at a lab-scale with the addition of reagents like frother, collector, depressant, activator, etc., for aiding the separation of coal from impurities.
Galena
The sulphidized lead minerals are subjected to flotation using xanthates or mercaptans and pine oil to produce a flotation concentrate which is cleaned two times to produce a high grade marketable lead concentrate. The flotation tailing from the lead section passes to a wet cyclone to make a primary sand-slime separation.
