Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.

1.1 Copper-nickel sulfide ore crushing stage. Adopt a two-stage closed-circuit crushing process. ① Use a jaw crusher for primary crushing. ② Use a cone crusher for fine crushing. ③ Use a vibrating feeder to screen out the products whose size meets the grinding requirements, while the oversized ones are returned to the cone crusher.

Nickel ore preparation involves a series of processes to prepare the ore for further processing, including crushing, grinding, and classification. These steps help to reduce the ore size, increase the surface area for chemical reactions, and separate the valuable nickel minerals from the gangue (unwanted material). 1. Crushing

Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...
