A method for the flotation of nickel and copper sulphide minerals from talcose bearing ores using an alkaline circuit in which at least one of the alkaline reagents is soda ash or ammonium hydroxide and following conditioning of the pulp with a collecting agent of the xanthate family to activate the nickel and copper sulphide materials, the pulp is conditioned with a flocculating agent to depress the host rock minerals and in which following flotation the rougher concentrate is further conditioned with a dispersant or a flocculant prior to the first cleaner float. |
