Centrifugation displaces surface depositions by washing and ML removal. Wash legs reduce surface depositions by partly displacing high impurity ML with feed. Crystallisation is a key step in the processing of battery materials such as nickel sulphate to achieve the desired product purity.
Nickel processing - Extraction, Refining, Alloying: 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

Conclusions This study assesses the environmental performance of the production of nickel sulfate that is used in Li-ion batteries. A cradle-to-gate LCA examines the environmental impacts and energy use of a typical HPAL hydrometallurgical process in Indonesia, that produces MHP from low-grade limonitic laterites.
Main process of producing nickel sulfate is solvent extraction process, which is called “Crowding organic bypass—solvent extraction (COB-SX).” COB-SX is unique and effective for not only nickel and cobalt separation, but also nickel and other impurities including magnesium.
If amount of nickel extraction at the exchange stage increases, amount of sulfuric acid increases at the Ni-recovery and it leads to high-cost operation. In order not to increase the cost, other method is necessary for reducing magnesium concentration of nickel sulfate.
The capacity of nickel sulfate production is 29,000 t/A. Nickel sulfate, which is low in magnesium, is required for large-capacity batteries of EVs, because magnesium reduces battery discharge capacity . It is difficult to separate magnesium and nickel by redox or neutralization, but solvent extraction can separate them.
The present study clearly demonstrates the importance of conducting a life cycle assessment (LCA) to systematically assess the environmental impacts of nickel sulfate production in Indonesia, a key emerging hub in meeting global battery-grade nickel demand.
The advantages of using nickel sulfate in batteries include: the raw materials are pure and the source of raw materials is stable, ensuring the quality and quantity are guaranteed and the impurities are few. The prepared nickel sulfate crystals have a high quality. The production process is clean and results in minimal environmental pollution. The disadvantage is that the production costs are high.
