Assessing the energy and greenhouse gas footprints of nickel laterite
Nickel is commonly present in two principal ore types sulfide and laterite ores. Historically, most nickel production has been derived from sulfide ores. While about Modern automated plants for processing laterites feature state-of-the-art technology and environmental compliance. Production plants range in nameplate annual capacity from 10 to 50 thousand metric tonnes of nickel contained in the final product(s).

Challenges in processing nickel laterite ores by flotation
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., The leaching rate of cobalt-nickel is over 95%, and the total yield is more than 90%. HPAL process started from 1959. The plants applying this process to treat nickel laterite ore include MoaBay in Cuba, Murrin Lateritic Nickel in Australia, Cawse Nickel/Cobalt, etc. (2) Reduction roasting-ammonia leaching process (Caron process).Cobalt Metallurgy SpringerLink

Extraction of Nickel from Garnierite Laterite Ore Using
In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China.

Hydro-Pyro Integration in the processing of Nickel
Other than the hybrid Caron process the only operating hydrometallurgical process for nickel laterites are HPALs. The first commercial HPAL plant started production in 1959 at Moa Bay in Cuba and still continues today and Sherrit a 50% joint venture (JV) partner in Moa is a partner in the construction of the similar Ambatovy project in technologies for extracting nickel and cobalt from nickel laterite ore. In the next few years, some plants using this technology will be operated in Indonesia. The production will be estimated to be 543,000 tons per year by 2025. On the other hand, HPAL will produce more than 26 million tonnes of residue, and it requires good management.Iron Recovery from Residue of Lateritic Nickel Leaching

Indonesia’s Nickel Industrial Strategy CSIS
Indonesia’s first plant to process nickel for use in batteries was commissioned in May 2021, with at least seven more projects in the pipeline. The progress of these high-pressure acid leaching (HPAL) projects will be key to future battery-grade nickel supply, at least in the near term. While Indonesia is rich in laterite ore resourcesThe SX-EW Method. SX-EW, or the Solvent Extraction Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore.
