The preconcentration of nickel (Ni) laterite ores ahead of Ni recovery by hydrometallurgical processing makes good economic sense. Since Ni-bearing minerals are often finely disseminated through laterite ores, liberation of minerals either high and/or low in Ni content is a prerequisite prior to any form of separation process.

Magnetic separation: Magnetic separation is used to separate nickel minerals that are magnetic from non-magnetic gangue minerals. Magnetic separators apply a magnetic field to attract and separate magnetic particles from the ore. Flotation: Flotation is a widely used beneficiation technique for nickel ores.

The ore sample used in the work was low-grade nickel sulfide ore provided by Jinchuan Group, China. The chemical composition of the ore analyzed by XRF (XRF, S8 TIGER II, Germany) was shown in Table 1. It can be seen that the valuable metals contained in the ore are nickel and copper, with the content of 4.63 % and 2.75 %, respectively.

Nickel is widely used in industrial processes and plays a crucial role in many applications. However, most of the nickel resource mainly exists as nickel oxide in laterite nickel ore with complex composition, resulting in difficulty in upgrading the nickel content using physical separation methods. In this study, high-grade ferronickel concentrates …

It is found that the maximum separation coefficient of nickel and cobalt is 1.2 × 10 4 at the extraction ratio of 1:1. Under this extraction ratio, the more extraction amount of cobalt, the less extraction amount of nickel. It realizes the effective separation of nickel and cobalt. Therefore, the best extraction phase ratio is regarded as 1:1.
