A B S T R A C T A method of activating zinc sphalerite mineral is pro- vided. Zinc sphalerite is crushed and ground in a known manner then cleaned and sent to an activating station. An ammoniated aqueous solution of CuCO3 or CuCl2 is used to activate the zinc sphalerite. This activator is a substitute for the heretofore universally used CuSO4 but is less expensive and superior in many ways. After activation a flotation agent is added and air bubbles are introduced into the aqueous media to cause the zinc to float to the surface.
