Abstract

Un método para concentrar mineral de laterita de níquel, que incluye las etapas de agregar cloruro de calcio (24) y un reductante (22) al mineral, calcinar (20) el mineral, estando presente el cloruro de calcio en una cantidad que es insuficiente para hacer la transferencia substancial de níquel a una fase de carbono, pero suficiente para promover la formación de níquel reducido en una forma magnética, recuperando el níquel reducido como una fracción magnética (30) por medio d separación magnética (28) y fundir la fracción magnética en un horno de arco eléctrico de CD (36) para producir un producto de ferroníquel (38).A method for concentrating nickel laterite ore, which includes the steps of adding calcium chloride (24) and a reductant (22) to the mineral, calcining (20) the mineral, calcium chloride being present in an amount that is insufficient to make the substantial transfer of nickel to a carbon phase, but sufficient to promote the formation of reduced nickel in a magnetic form, recovering the reduced nickel as a magnetic fraction (30) by means of magnetic separation (28) and melting the fraction magnetic in a CD electric arc furnace (36) to produce a ferronickel product (38).
