Electromagnetic Separation of Copper Iron Sulphides

Feb 09, 2018 The ore passing from the furnace is cooled and fed to a second Wetherill-Rowand separator which removes the chalcopyrite as a magnetic product; the concentrate from this machine carries from 12 to 20 per cent. copper, and the tailing from 0.2 to 0.5 per cent. copper

Magnetic separation-sulphuric acid leaching of Cu–Co–Fe

Oct 01, 2014 The matte sample was crushed, wet ground and then magnetic separated to produce magnetically susceptible concentrate (mainly Co–Fe alloy). 95.75% of cobalt was recovered by magnetic separation and 87.8% of copper and 44.39% of iron remained in the tailings.

Utilization of high-gradient magnetic separation–secondary

Jun 01, 2019 The flotation tailings were separated by high-gradient magnetic separation, and the copper leaching rate from the magnetic concentrates was 26.85% of the raw ore. The copper leaching rate from the magnetic tailings was 26.95% of the raw ore, with a total recovery rate of 86.02%. 3.

Magnetic separation of weakly magnetic copper minerals

Abstract: High Gradient Magnetic Separation of chalcopyrite and bornite, both weakly magnetic copper minerals with mass susceptibilities of about 0.1 × 10 -6 m 3 /kg and 0.2 × 10 -6 m 3 /kg respectively, has been performed. Initially pure mineral samples were processed before turning to copper samples with decreasing content of the minerals. These were: a concentrate, flotation tailings and

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
