Abstract
A method for the depression of non-sulfide, silicate gangueminerals is provided wherein the depressant is either a polymericmaterial comprising recurring units of the formula:-[-X-]-x-[-Y-]-y -[-Z-]-z wherein X is the polymerization residueof an acrylamide or mixture of acrylamides, Y is an hydroxy groupcontaining polymer unit, Z is an anionic group containing polymerunit, 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 about50 %, or a mixture of said polymer and a polysaccharide.20 claims
