Abstract: 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.

Abstract translation: 本发明提供了通过泡沫浮选从含有它的原料中回收所需金属值的方法。 在粉碎步骤中，使用包含12％至30％铬的铁和铬钢合金的粉碎介质将原料粉碎。 在调节步骤中，将原料与硫脲和/或草酸作为主要浮选试剂接触。 调理步骤包括粉碎步骤，其中加入一定量的初级浮选试剂和获得预处理的粉碎原料。 调理步骤还包括任选的调理整理步骤，其中预处理的粉碎的原料和液体的混合物经受搅拌，并且从精制步骤获得经调节的粉碎原料。 在回收步骤中，通过泡沫浮选从预处理或调节原料回收至少一些所需的金属值。
