A Comprehensive Recovery of Copper-Iron Experimental Research in the Copper Smelting Slag

Abstract:

With the depletion of mineral resources, more attention is paid on the secondary resources to recover valuable metals. In this paper, a research is carried out to recover copper and iron from copper smelting slag by flotation and magnetic separation. The influence of grinding fineness and collectors on flotation of copper are investigated. A copper concentrate is obtained by flotation and an iron concentrate is obtained by magnetic separation in the closed circuit flowsheet. The copper concentrate contains 18.86% Cu with a recovery of 72.36%, and the iron concentrate contains 52.24% Fe with a recovery of 70.87%.
