The breadth of applicabi1 tY of such alternative depressants remains unknown and .. Experimental Conditions With each ore sample, a series of froth flotation
several methods that are useful for examining froth flotation processes: .. Figure 12: Effect of cyanide depressant on flotation of minerals as a function of pH. It is.
cyanide is used as a depressant in alkaline conditions for the selective depression of pyrite from chalcopyrite during the froth flotation process, leading to
Huntsmans POLYMAX®, UNIMAX®, DETA and TETA flotation depressants and dispersants for This increases the selectivity of flotation, rendering certain minerals gangue is therefore less likely to float or be entrained in the froth phase.
The process of froth flotation entails crushing and grinding the ore to a fine size. This fine Depressants are chemicals that inhibit the flotation of minerals.
