Abstract

A method for the depression of non-sulfide, silicate gangue minerals is provided wherein the depressant is either (1) a polymeric material comprising recurring units of the formula: -[-X-]-x -[-Y-]-y -[-Z-]-z wherein X is the polymerization residue of an acrylamide or mixture of acrylamides, Y is an hydroxy group containing polymer unit, Z is an anionic group containing polymer unit, x represents a residual mole fraction of at least about 35 %, y represents a residual mole fraction of from about 1 to 50 % and z represents a residual mole fraction of from about 0 to about 50 %, or (2) a mixture of said polymer and a polysaccharide.
