Nickel extraction from primary resources such as ores/minerals (sulfides, arsenides, silicates, and oxides) including the ...
A steadily increasing demand for nickel has without doubt raised the importance of the worlds nickel reserves and applied more focus on the techniques used for extraction of nickel from its ores. The Caron Process is one such technique which is effective by reduction of the ore by roasting followed by ammonia leaching of the reduced ores.

Nitric acid pressure leaching process (NAPL) uses nitric acid as the leaching medium to produce cobalt and nickel raw materials. Based on the benefits of nitric acid pressure leaching process for laterite ore, this paper proposes a process of "nitric acid pressure leaching-neutralization precipitation-reductive ammonia leaching separation".
Based on these results, the CLR process is the preferred leaching mechanism for the nickel extraction-mineral carbonation process being developed. However, it does still present challenges. In the current system the extraction rates are insufficient to achieve 50% recovery of Mg and Ni in 3 h. The solid/liquid ratio is also low.
The solvent extraction process has been developed for purification and separation of various elements in the laboratory and industrial scales. In this regard, nickel solvent extraction (SX) has been carried out on both scales. There are various extractants used for the extraction of nickel from leach liquor.
The cobalt extraction process is compared with the copper and nickel production process to identify its relative importance. Allocation is avoided in this study by assuming that no byproduct is leaving the system. ... Primary extraction, nickel reduction and smelting; electricity usage, coal usage: Titanium oxides (Farjana, Huda, Mahmud, & Lang ...
The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solid-state nickel extraction method that recovered nickel values into ferronickel …
In the realm of industrial processes, there exists a notable focus on the extraction of valuable metals from waste materials, as it holds considerable potential for generating both economic and environmental advantages [].Among the several metals, nickel is well recognized as a highly coveted resource due to its extensive range of applications across multiple industries.
extraction plant as nickel and cobalt. All metals for which an extraction reagent is available can be extracted using advanced Outotec VSF solvent extraction technology. After solvent extraction other valuable metals like copper can typically be recovered, for example as cathodes or sulfide precipitates.
