We already reported some results obtained from a series of experiments on “Extraction of Nickel from Laterites or Garnierite ores by Segregation Process”, which were carried out in a laboratory scale.
Using a rotary kiln, flotation and magnetic separation, the segregation process has been done on a semi pilot plant.
Using a rotary kiln, flotation and magnetic separation, the segregation process has been done on a semi pilot plant.
The nickel concentrates have been obtained in 85-90% Ni recovery and 12-25% Ni content.
The high Ni concentrats could be graded up to 35-40% Ni by combined process of flotation and magnetic separation.
