Lateritic nickel ore deposits
Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (Hydrometallurgical Processing of Nickel Laterites—A Brief Overview On The Use of Solvent Extraction and Nickel/Cobalt (PDF) Hydrometallurgical Processing of Nickel

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical Knowledge of the mineralogy of any ore is essential to achieve optimum plant design, processing conditions and economic return on investment.

Nickel laterite processing and electrowinning practice
Processing of laterite ores traditionally consists of a two stage process using fossil fuels (eg., coal, oil, The Rezh nickel plant, with an output of 9000 tonnes per year of nickel contained in Fe–Ni, was commissioned in 1936 and produces several grades of ferronickel for consumption within the former Soviet Union.The emergence of the battery society has resulted in an unprecedented strain on the supply of battery metals, such as nickel, cobalt, and manganese. Consequently, there is an urgent need to develop processing technology for low-grade nickel laterite ores, which are abundant in resources but challenging to process using Hydro–pyro integration in the processing of nickel laterites

Processing of Nickel Laterite Ores on the Rise
The 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 Despite the growth in nickel laterite processing, upgrading these ores remains a challenge. This is mainly because of their complex and variable mineralogy and the lack of definite nickel-bearingPreconcentration strategies in the processing of nickel laterite ores

Legislation needed to push for ore processing plants
February 13, 2022 12:00am. MANILA, Philippines — The Mines and Geosciences Bureau has called for appropriate legislation to compel mining companies to put up ore processing plants which couldtechnologies 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 Industry

Albania has been mining nickel ores for decades, but there are no processing facilities; thus, Albania exports only the lateritic ore. Bosnia Herzegovina and Serbia have significant Ni-Co deposits, but The processing plant will be located within two kilometres of the port, thereby simplifying acid transport and other logistics, as well as keeping operating costs down.

Process simulation and exergy analysis of two nickel laterite
Nickel was mostly extracted from nickel sulphides though it was the lesser reserve (40%) of nickel ores as sulphides were easier to process (Jessup and Mudd, 2008). However, as these sulphide based reserves are slowly depleting, there is an increasing interest towards processing abundant nickel laterite deposits (Agatzini-Leonardou et Of the nickel mines operating in the country, only Nickel Asia Corporation (NAC), the country’s top producer of nickel, processes its nickel laterite ores.
