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 × Ni M Ni × Ni × 100 % where m Ni is the mass of the magnetic product, g; Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g; and Ni is the nickel content in the reduced laterite ore, wt.%.

Extraction of Nickel from Garnierite Laterite Ore . In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash feldspar, forsterite,

The beneficiation process of nickel ore,copper-nickel

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,

Nickel processing - Extraction and refining | Britannica

2 · Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

The beneficiation process of nickel ore,copper-nickel

Copper-nickel separation technology is divided into two types: copper-nickel mixed concentrate separation and high matte separation technology. Generally, the former is used for copper-nickel minerals with relatively coarse grain size and not closely related to each other, and the latter is used for copper-nickel minerals with fine grain size and densely interspersed ore.

SEPARATION OF NICKEL FROM ASBESTOS ORE - JOHNS

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.
