Abstract
A method in the flotation with foam of sulfur-containing minerals containing arsenic together with sulfur compounds of cadmium, mercury, antimony and bismuth present in them, obtained from ores and ore products, characterized by the steps of adding to a pulp of said calcium ion-forming materials in amounts sufficient to obtain a calcium ion concentration comprised between 150 and 1500 mg/l of the aqueous phase, preferably between 300 and 1200 mg/l; adjust the ph of the pulp to a value greater than 11.5; heating the pulp at a temperature comprised between 30 and 50º c, preferably between 35 and 45º c; and adding to the pulp copper (II) ions in an amount such that the molar ratio of the arsenic contained in the solid phase to the added amount of copper (II) ions is in the order of 50: 1 to 500: 1, preferably from 100: 1 to 250: 1.
