Chrysotile mining in Quebec has produced about 2 Gt of serpentinite residue. The present study investigates the magnetic separation of serpentinite residue from Quebec to produce a non-magnetic feed stock for mineral carbonation. This study also scrutinizes the quality of the magnetic fraction recovered for use as a source of iron ore. The optimum conditions of magnetic separation were obtained with multiple pass approaches; at 40% initial pulp density and 7.5 x 10(-3) testa (T) magnetic intensity with a mean particle size of 75 urn. The process removed about 71% of the iron impurities from the initial feed. The final non-magnetic fraction is rich in magnesium silicates with a low iron oxide concentration of 3.4%. The concentrations of iron oxide and silica in the final recovered magnetic fraction are 79% and 8.6%, respectively. (C) 2015 Elsevier B.V. All rights reserved.
