Copper losses to slags obtained from the El Teniente

2009-8-26  The El Teniente slag cleaning furnace process is based onan intensive reduction of magnetite and copper content inmolten slag produced at the El Teniente converter, byinjection of a solid, liquid or gaseous reductant directly into the molten slag through specially designed tuyeresfollowed by sedimentation stage. The reduction ofmagnetite decreases the slag viscosity and enhances thesettling of copper enriched phase. The molten productsobtained after the settling stage are, a discard slag with acopper content less than 1 wt.% Cu, and a high gradecopper matte with 60–70 wt.% Cu. The decoppered slag ispoured into ladles, and then transported to dump by pot-carriers. The high-grade copper

RECOVERY OF COPPER FROM COPPER SLAG AND

2014-9-8  The pyrometallurgical processing of copper concentrates generates large amounts of copper-containing slag. Management options for this slag include recycling, recovery of metal values, production of value added products and disposal (Gorai and Jana, 2003). However, there are no universal methods to recover copper from copper-bearing slags as the chemical and phase composition of a slag depend on factors such as the type of ore mined and the type of pyrometallurgical process
