Abstract

Flotation in one of the important operations in ore beneficiation process. Chemical auxilliaries play an important role in the froth flotation process 1. In order to obtain a successful flotation of slimy sulphide ores, two types of chemical auxilliaries are basically in use i. e. ( i ) a hydrocolloid acting as flocculent for gangue material, commonly referred as a depressor and (ii) a collector or a metal reagent, which conditions the mineral surface ( by adsorption and making it more hydrophobic ) so that it will rise to the surface when a frother is added. Besides these, certain other chemicals are also sometimes used to augment the action of either depressor or collector 2 .
