Metallurgical Beneficiation of Iron Laterite Ores with the ...

A new process is developed for metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel-cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions in the temperature range 1100-1200°C, the fragmentation of the roasting product, and the magnetic separation of metallic and slag phases.

Laterite Ore - an overview ScienceDirect Topics

The laterite ore is dried and reduction roasted in multihearth roasters in an atmosphere containing hydrogen and carbon monoxide in the absence of air. Nickel and cobalt are selectively reduced to the metallic form and thus rendered amenable to ammoniacal leaching, while iron remains as insoluble oxides and silicates.
