The invention provides method to recover, by means of froth flotation, a desired metal value from a feedstock containing it. In a comminution step, the feedstock is comminuted using comminuting media of an iron and chrome steel alloy comprising from 12% to 30% chrome. In a conditioning step, the feedstock material is contacted with thiourea and/or oxalic acid as primary flotation reagents. The conditioning step comprises the comminution step, in which a quantity of the primary flotation reagent/s being added and preconditioned comminuted feedstock material being obtained. The conditioning step also comprises an optional conditioning finishing step, in which a mixture of the preconditioned comminuted feedstock material and a liquid is subjected to stirring and with conditioned comminuted feedstock material being obtained from the finishing step. In a recovery step, at least some of the desired metal value is recovered by froth flotation from the preconditioned or conditioned feedstock.
