Abstract

Oxidized ores are subjected to froth flotation in the presence of a soluble sulphide, e.g. sodium sulphide, and a soluble alkali silicate, e.g. sodium silicate, the amount of silicate added being restricted to approximately the minimum amount necessary to effect deflocculation of the gangue, this amount usually being of the order of 0,1 lbs. silicate per ton of ore. The ore is preferably somewhat coarsely crushed, for example so as to pass a screen having 60 meshes per inch. The concentration of a mixed oxide and sulphide copper ore is described, the sulphide being first floated using potassium xanthate and pine oil as flotation agents and the oxide being subsequently recovered by adding sodium sulphide, 0,1 lbs. per ton of sodium silicate, fuel oil and pine oil. The use of ammonium sulphide is also referred to. To facilitate dewatering of the tailings and filtration of the concentrate an alkali chloride or alkaline earth chloride, with or without a small amount of a soluble soap, may be added to the tailings or concentrates to re-flocculate the gangue. Specifications 136,255, 166,888, and 218,012, [all in Class 82 (ii), Washing granular &c.], are referred to.
