Dehydroxylation and dissolution of nickeliferous goethite in New Caledonian lateritic Ni ore

TL;DR: In this article, a new method was used for selective leaching of nickel and cobalt, as well as for preparing iron phosphate intermediate material by atmospheric phosphoric acid leaching on limonitic laterite.

TL;DR: In this paper, the sulphidation of a nickeliferous lateritic ore was investigated between the temperatures of 450-1000°C and sulphur additions of between 25 and 900 kg of sulphur per tonne of ore.

TL;DR: In this article, a systematic study was performed to establish the reaction mechanism involved for recovery of nickel and cobalt from chromite overburden (COB), Sukinda, Orissa using pure culture of Aspergillus niger.

TL;DR: Thermal transformation of schwertmannite can greatly increase As mobility and has major consequences for As/Fe/S speciation under reducing conditions, and further research is warranted to unravel the wider implications for water quality in natural wetlands.

TL;DR: In this article, the authors introduce the concept of iron oxides and their properties, including surface chemistry and Colloidal stability, as well as their properties in terms of surface area and porosity.

TL;DR: Crystal structures of clay minerals and their X-ray identification TLDR; Crystal structures of clay minerals are studied using X-ray diffraction, which remains a basic tool despite the availability of other techniques.

TL;DR: An essential volume in industry and to all researchers who, whatever their background and level of experience, are interested in this rapidly expanding field as discussed by the authors, is a good resource for anyone interested in the field.
