Document Type and Number:
WIPO Patent Application WO/2010/078787
Kind Code:
A1
Abstract:
A beneficiation process for enriching nickel and/or cobalt involves the steps of dividing nickel laterite into limonite type ore and serpentine type ore to beneficiate separately; classifying by screening at least one time after washing the ore; beneficiating separately the products of the various grades obtained; further classifying by gravity separation and magnetic separation to obtain the target concentrate. The concentrate thus obtained by dividing said nickel laterite into limonite type ore and serpentine type ore to beneficiate separately provides higher quality and a higher recovery rate.
