Calcination of low-grade laterite for concentration of Ni

2010-3-1  Since, the laterite ore usually contains Fe which has magnetic properties, the concentration of Ni is not an easy task. In order to enable the selective concentration of nickel by magnetic separation, the calcination of laterite was carried out prior to the magnetic separation. The aim was to alter the crystalline structure of Fe species and
