The Ni grade increased by 17% and 36% for the saprolite and intermediate samples (i.e. ore S and I), respectively. The proportion of fine particles in the ores increases after gravity separation. Interestingly, upgrading nickel in the ore I sample resulted an acceptable level of Ni% for this ore for further conventional processes.
