In froth-floatation process, what is the depressant used in …

In froth-floatation process, depressants help to separate two sulphide ores by selective prevention of froth formation by one ore and allowing the other to come into froth. For example, in order to separate two sulphide ores (ZnS and PbS), NaCN is used as a depressant. It selectively allows PbS to from the froth, but prevents ZnS from coming to froth. This happens due to the …

Flotation Depressants

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. This is because the froth is becoming purer as the unwanted mineral, the iron pyrite, is being cleaned off of the bubble.
