Copper Slag Magnetic Separation

Improving Beneficiation of Copper and Iron from Copper

An earlier work noted that magnetic separation is a feasible way to recover iron from the tailings of waste copper slag flotation. Unfortunately, the iron grade of magnetic products and the recovery of iron by the magnetic separation process is relatively low, only 52.21% and 38.09%, respectively, due to the

Liberation and Enrichment of Metallic Iron from

20-02-2021· Fayalite in copper slag is reduced to metallic iron and silica through carbothermal reduction, and zinc and lead are enriched in the dust.11 Kim et al.8 performed grinding magnetic separation to recover the metallic iron from reductively roasted copper slag obtained at 1250°C and obtained a concentrate of 66.10% Fe content with Fe recovery of 87.03%.

20-03-2020· This paper proposes an eco-friendly process to synchronously utilise copper slag and ferruginous manganese ore by co-reduction followed by a magnetic-separation process to solve those problems. In the process, MnO 2 within FMO acted as a catalyst to promote the reduction of fayalite and copper sulphide contained in CS, and thus improve the metallisation rate of Fe and Cu.

Improving Beneficiation of Copper and Iron from Copper

The roasting-magnetic separation process is the route to convert the metals into a desired phase, which can be easily separated from the slag through mixing copper slag with calcium oxide as fluxes and carbon as a reducing agent, then roasting the mixture at a temperature of about 1200–1300 C, followed by magnetic separation to

20-06-2018· In this work, a selective co-reduction and magnetic separation process was developed to economically and eco-friendly clean copper slag and synchronously upgrade nickel laterite. Through the innovative process, not only the valuable metals, such as Fe, Ni and Cu, can be recovered, but also the hazardous elements can be removed from copper slag, including As, Pb and Zn.
