The extraction of nickel from the limonite ore initially correlates with the goethite reacted (Fig. 4), suggesting that the nickel is homogeneously distributed throughout the goethite and that maghemite contains only a minor amount of the total nickel present in this ore.

Prohibition of the export of nickel ore. Through successive policies implemented between 2009 and 2019, the Indonesian government has, as of late April 2022, progressively banned the export of nickel ore, requiring nickel to be processed domestically for export. The export of nickel ore was first outlawed as early as January …

Through long weathering processes, Ni2+ replaces Mg2+ and Fe2+ in the lattice of corresponding silicates and ferric iron oxides, and is closely in conjunction with iron oxide and silicate minerals [8]. The concentration of nickel in an ore-body is very low, and typical nickel content in Chinese laterite ore is less than 1%.

The sulphidation of a nickeliferous lateritic ore was studied at temperatures between 450 and 1100 °C and for sulphur additions of 25–1000 kg of sulphur per tonne of ore. The experiments demonstrated that the nickel could be selectively sulphidized to form a nickel–iron sulphide. It was found that both the grade and the sulphidation degree ...

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., (1961) and …

For both acid load cases, the nickel extraction was more sensitive to temperature increases whereas cobalt extraction became insensitive at lower acid load. At both 0.325 and 0.275 acid to ore ratios neither nickel nor cobalt extractions dropped below 90% even at the lowest temperature studied (240 °C).
