The magnetic separation concentrated 30 percent of the nickel originally present into a nickel-enriched fraction comprising 17 percent by weight of the original sample. The nickel-enriched fraction is then passed through a centrifugal impact mill manufactured by Entoleter, Inc. to subdivide or open the residual fiber bundles, making them more bulky and easier to subsequently separate and remove.

2021-4-29 (2) The novel chloride roasting–magnetic separation process was employed to extract Ni from the magnesia–nickel silicate ore with the addition of the Sc-bearing red mud. The addition of red mud enhanced the transformation of nickel silicate to a strongly magnetic mineral dominated by metallic Ni, and Fe 2 O 3 transformed to Fe 3 O 4 and metallic Fe.

2020-9-24 The beneficiation process of nickel ore . Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores,
