Galena - Sphalerite Flotation & Separation Method
The tailing of the lead flotation stage passes direct, or, as explained above, through a thickener, to the zinc conditioner, where copper sulphate is added to activate the zinc minerals. Lime is generally introduced at this point to depress pyrite and to maintain the alkalinity of the pulp at the required pH value, usually between 8.0 and 9.0.
