Recovery of iron from copper slag via modified roasting in

2020-6-4  Therefore, Jiao et al. proposed an innovative approach to recover iron from copper tailings via low-temperature direct reduction and magnetic separation, in which copper slag was reduced by pulverized coal and then recovered by magnetic separation, and the reduced iron powder with iron grade above 90% and recovery ratio of 95% was finally obtained. Generally, reduction and beneficiation of iron from copper slag result in high iron grade and recovery of reduced iron powder, but coal

Copper Recovery from Yulong Complex Copper Oxide Ore

2017-5-25  As seen in Fig. 4c, the delafossite was wrapped in the limonite and thus they were recovered together by high-gradient magnetic separation. It is found from Fig. 4d that the copper in the tailing was mainly in the form of very fine covellite and was dispersed into gangues and limonite. Therefore, it is very difficult to further increase the copper recovery, and the developed process is effective to utilize

Mineral Liberation of Magnetite-Precipitated Copper Slag

2016-8-11  Through magnetic separation, iron was separated into high- and low-iron-bearing concentrate and tailing for specific applications. A magnetic field intensity of 100 mT yields an iron grade of approximately 60 mass pct for the concentrate of 50-µm under-sieve HV crushing feeding with a recovery of approximately 60 pct.
