Dual effects of sodium sulfide on the flotation behavior

Dual effects of sodium sulfide on the flotation behavior

Abstract. This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na 2 S183;9H 2 O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10 1 10 2 mol/L.

This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinccyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.

Sodium sulfide

Sodium sulfide

Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S183;9H 2 O. Both are colorless watersoluble salts that give strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide , which smells like rotten eggs.
