Apr 01, 2019· Direct reduction-magnetic separation is an efficient way to recovery iron from copper slag, where iron and copper minerals can be transformed into the desired phases (metallic Fe and Cu) by direct reducing the mixture of copper slag and carbon as a reductant at about 1200–1300 °C [,,]. In the direct reduction process of copper slag, the fayalite and copper sulfide are reduced to metallic iron
Oct 01, 2014· So the magnetic separation was used to separate the cobalt from copper and achieve the separate recovery of cobalt and copper. The MS-SAL process consists of a magnetic separation from ground matte to produce concentrate (magnetic separation stage), followed by the sulphuric acid leaching of the concentrate (sulphuric acid leaching stage).
Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron min-erals from the slag because the iron mainly occurs in fayalite. A new technology of coal-based direct reduction-magnetic separation process was developed to recover iron from the slag assaying 39.85% Fe total and 0.33% Cu. The results show that the final iron concentrate, assaying 90.68% Fe

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
The process first crushes the waste copper slag below 1 mm (first crushing step), followed by carbon reduction at $1225^{\circ}C$ for 90 min (carbon reduction step). And then, resulting material is again crushed to $-104{\mu}m$ (second crushing step), followed by wet magnetic separation (wet magnetic separation step). Using the developed process, a magnetic product containing more than 66 wt.% iron
