DEPRESSANT FOR FLOTATION SEPARATION OF POLYMETALLIC SULPHIDIC ORES

A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhoti...

Zusammenfassung:	A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing. The depressant consists of a cross-linked starch chemically combined with a polyacrylate and sugar free lignin sulphonate.
