“…The copper-nickel sulfide ores account for 30-40% of the total nickel ores, while the nickel oxide ores account for the remaining 60-70%. Despite the small proportion of copper-nickel sulfide ores, the production of nickel from nickel sulfide ores account for more than 60% of the world's total nickel production due to its simpler production process [31]. In China, copper-nickel sulfide ores and nickel oxide ores account for 87% and 13% of the total national nickel reserves, respectively; nickel is generally produced from copper-nickel sulfide ores in China [32].…”

Various methods, such as electrochemical purification, chemical precipitation, solvent extraction, and ion-exchange resins, have been extensively employed for the removal of copper from nickel anolytes. However, these methods exhibit several significant drawbacks when applied in industrial settings. For instance, electrochemical purification fails to efficiently manage nickel anolyte solutions with low copper content. Chemical precipitation presents challenges in residue management and incurs high production costs for precipitants. Solvent extraction raises concerns related to toxicity, while the use of ion-exchange resins demands meticulous selection of suitable materials. In this review, we present a comprehensive review of the nickel removal methods used for nickel anolyte purification, electrochemical purification, chemical precipitation, solvent extraction, and ion-exchange resins. We also examine the suitability and benefits of each technique in industrial settings. The ion-exchange method has drawn significant attention due to its strong selectivity and small adsorption quantity. The ion-exchange separation process does not generate any slag, and the ion-exchange resin can be recycled and reused; this method has great potential in a wide range of applications.

“…The nickel mined comes from two types of ore deposits, magmatic sulfide deposits and laterites. Sulfide nickel ore, due to a long-term excavation, has seen a constant decline in production in China ( Murofushi et al, 2022 ), and more than 60% of nickel ore is laterite nickel ore ( Pandey et al, 2023 ) presently. Nevertheless, due to Indonesia’s embargoes on raw ore exports ( Hobson, 2013 ; Shi and Ju, 2023 ), diminishing production from Philippines’ mines ( Lee, 2017 ), and the Russian-Ukrainian war causing significant restrictions on the export of nickel ( Erickson, 2022 ), the price of nickel ore shows an overall upward trend, with the discord between supply and demand becoming increasingly conspicuous.…”

Objective: Niccolite, a rare nickel arsenide mineral, has emerged as a promising source for nickel extraction. However, its processing is limited and often associated with toxicity concerns. This study aims to search for efficient separation of arsenic during the roasting process of niccolite.Methods: The arsenic-containing phase was optimized through changing the contents of oxygen, additive S, and additive FeS in the system to achieve efficient separation of arsenic during the roasting process of niccolite. Thermodynamic analysis was performed using the equilibrium composition module with HSC Chemistry.Results: The thermodynamic results showed that in direct roasting, the product contained ferric arsenate which immobilized arsenic in the solid phase, increasing the difficulty in separation. In the presence of sulfur, the arsenic may escape completely in the form of gas (As2O3, As4O4, As4O6). The use of FeS as the reductant significantly reduced the residual arsenic content.Conclusion: The FeS reduction in roasting process is an optimal strategy for arsenic removal from niccolite. This provides a novel technique for nickel extraction in industry.
