The air was induced into the pulp by turning the knob on the stem of the Denver flotation cell. The resulting froth was continuously skimmed off into a clean dry container and collected the concentrate until no froth was no more formed. Subsequently, the same process was followed using 4 g and 6 g of CS under the same flotation conditions.
