Pre-concentration of nickel in laterite ores using ...

2019-9-1  In the current work, nickel was upgraded in ore I (sample from the intermediate zone between saprolite and limonite) from 1.1% to 1.5% at 70% recovery. It should be noted that ore I has the highest amount of quartz among the tested samples . This should have helped upgrading nickel in this ore using gravity separation.
