Production of Ferronickel Concentrate from Low-Grade Nickel

The production of ferronickel concentrate from low-grade nickel laterite ore containing 1.31% nickel (Ni) was studied by the non-melting reduction magnetic separation process. The sodium chloride was used as additive and coal as a reductant. The effects of roasting temperature, roasting duration, reductant dosage, additive dosage, 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. Garnierite was the Ni-bearing mineral; the other main minerals were potash Extraction of Nickel from Garnierite Laterite Ore Using

Comprehensive Review on Metallurgical Upgradation Processes of Nickel

Hydrometallurgy. Hydrometallurgical process for nickel sulfide ore was developed in 1970s, which is to transfer valuable metals to liquid phase from solid ore by chemical leaching, and then extracts valuable metals by solvent extraction, chemical precipitation, crystallization, and other means [ 25 27 ].Key words: low-grade nickel−copper sulfide ore; chlorination roasting; synchronous extraction; phase evolution; kinetics 1 Introduction After years of continuous mining, the high-grade nickel sulfide ore is facing exhaustion and the low-grade nickel−copper sulfide ore will replace it to be the main feedstock in theCo-extraction of valuable metals and kinetics analysis in

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 and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into In this case, the ferro-nickel alloy with nickel grade 7.90% and iron grade 77.32% was prepared successfully from the low-grade saprolitic ore with nickel content 1.82%.
