SEPARATION PROCESS FOR VOLATILE METALS, SUCH AS LEAD, ZINC AND CADMIUM FROM SULPHIDE CONCENTRATES

SEPARATION PROCESS FOR VOLATILE METALS, SUCH AS LEAD, ZINC AND CADMIUM FROM SULPHIDE CONCENTRATES

The invention relates to a method for producing zinc, cadmium, lead and other easily volatile metals from sulfidic raw materials in a pyrometallurgical process. In the method, zinc sulfide concentrate is fed into molten copper in atmospheric conditions, at a temperature of 1,450 - 1,800 DEG C, so th...

Zusammenfassung:The invention relates to a method for producing zinc, cadmium, lead and other easily volatile metals from sulfidic raw materials in a pyrometallurgical process. In the method, zinc sulfide concentrate is fed into molten copper in atmospheric conditions, at a temperature of 1,450 - 1,800 DEG C, so that the zinc, lead and cadmium are volatilized, and the iron and copper remain in the molten metal or in the metal sulfide matte created in the furnace.
