ABSTRACT:
This process for enriching nickel-bearing oxide ore comprises pulping the ore, washing the pulped ore for at least 1 minute, sorting the washed ore in a damp environment so as to separate at least one fine fraction from a granular fraction, subjecting the fine fraction to densimetric separation at a dividing density of between 1.7 and 2.5 and recovering the light fraction separated off as enriched ore.
