Ferric leaching of copper slag flotation tailings

Jan 01, 2009· Copper can be recovered from the slags by froth flotation after cooling, crushing, and grinding. The obtained Cu-concentrate is sent to the pyrometallurgical process. If grinding is not fine enough for efficient flotation, copper is lost in tailings. In this paper, the ferric leaching of slag flotation tailings is studied.

The Recovery of Copper from Smelting Slag by Flotation

Feb 08, 2017· Consequently, flotation was attempted to recycle Cu in slag containing copper sulphide components. Three key factors affecting flotation were ascertained, namely, grinding fineness, the collector and the pH value, while the recovery of Cu estimated by ICP and XRF. Copper concentrate grading at 14.47 with 79.66% Cu recovery was obtained, in the
