Direct reduction refers to the process of reducing iron minerals in copper slag to metallic iron particles below the melting temperature of copper slag [].Using direct reduction–magnetic separation technology to recover iron resources in copper slag has fair recovery effect and short reaction time, which is the development trend of …

Deep Reduction to Obtain Fe–Cu Alloy Followed by Magnetic Separation. An alternative route to reduction of slag in liquid state, the reduction process can be also conducted in solid state of the slag [143, 162, 163]. Copper slag, carbon and additives like CaO are blended as an input material, where pellets can be produced [143, 162, 163].

Iron recovery from lead smelting water-quenching slag by "roasting–grinding–magnetic separation" method ... proposed two routes for the selective recovery of lead, copper, nickel, and zinc from lead slag under optimum conditions. The leaching rates of lead, copper, zinc, and nickel were 92%, 60%, 70%, and 66%, …

1. Introduction. Copper slag (CS) is a kind of hazardous waste generated during the copper-smelting process from copper sulfide concentrates (Potysz et al., 2017).About 2–3 tonnes of CS are generated per ton of produced blister copper (Potysz et al., 2017, Gbor et al., 2003).Because of the increasing demand of copper and rapid …

Copper slag is a solid pollutant with high recyclability. Reduction and separation are regarded as effective disposal methods. However, during the melting process, the separation and migration ...

Finally, the treated copper slag was crushed and grinded down to 40 μm, and two fractions were obtained by magnetic separation. The magnetic fraction (85%) was mainly comprised of magnetite, while the non-magnetic fraction (15%) had 5–10 wt. % Cu. Considering the experimental results, 7.5–18 kg Cu/t slag might be recovered from …

An innovative technology for direct reduction-magnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying 40.33% Fe total and 0.65% Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.

During the pyrometallurgical treatment of the nickel-bearing laterite in the plant of G.M.M. S.A. LARCO, slag is produced after treatment in electric-arc furnace (EAF) that contains 0.10 to 0.20 % Ni.

The results of magnetic separation are shown in Table 6. The results show that the increase of water content adversely affects magnetic separation, as the grade of the magnetic product drops from 0.98 % to 0.72 % Ni; the corresponding yield reduces from 25.82 % to 24.76 %, and the recovery reduces significantly from 81 % to 66.5 %.
