What is the role of depressant in froth floatation process?

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth

Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer

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
