Flotation Depressants Mineral Processing Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color.

The reductant is demonstrated to desorb the collector from the mineral surface in a reduced condition or even form hydrophilic species. The oxidant generally oxidizes the mineral surface and causes it to be hydrophilic. These organic depressors are declared to be hydrophilic and cover the mineral surface to prevent the adsorption of collectors.
