    The tails produced in the first differential flotation step is followed by a pyrite and pyrrhotite flotation stage using xanthate and MBT, leaving the cobalt minerals in the flotation cell tails. The cobalt minerals are then floated by using sulphuric acid to decrease the pulp pH to 4. Sodium sulphide is conditioned in the pulp. Cobalt is floated using a combination of xanthate and dithiophosphate and/or MBT. Depending on the cobalt
