The Piauí laterite (NE Brazil) was initially evaluated for Ni but also contains economic concentrations of Co. Our investigations aimed to characterise the Co enrichment within deposit; by understanding mineralogy we can better design mineral processing target recovery. is heterogeneous on mineralogical and lithological scale differing from classic schematic profiles nickel laterites, while the...

An alternative laterite nickel ore processing using sulfuric acid as a leaching agent to produce class 1 raw material for electric vehicle batteries produces natrojarosite residue by-product during the precipitation of iron and aluminum step. The contained high sulfur, which is challenging utilize an source steel manufacturing since sulfur can contaminate product. This study focuses on eliminat...
