magnetic separator for nickel ore

Separation and recovery of iron and nickel from low-grade

Nov 01, 2020· The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g

Pre-concentration of nickel in laterite ores using

Sep 01, 2019· Of course, upgrading nickel using magnetic separation highly depends on the ore mineralogy and mineral liberation, and if nickel is associated with magnetic minerals. Table 3 also shows that the percentage of iron increases (by ~70%) in the magnetic product for ores S and I, but not for ore L. On the other hand, more silicon bearing minerals

Efficient enrichment of nickel and iron in laterite nickel

Mar 01, 2020· The process of deep reduction and magnetic separation was proposed to enrich nickel and iron from laterite nickel ores. Results show that nickel–iron concentrates with nickel grade of 6.96%, nickel recovery of 94.06%, iron grade of 34.74%, and iron recovery of 80.44% could be obtained after magnetic separation under the conditions of reduction temperature of 1275 °C, reduction time
