Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.

The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.

Sediment-hosted Pb-Zn deposits contain the world's greatest lead and zinc resources and dominate world production of these metals. They are a chverse group of ore deposits hosted by a wide variety of carbonate and siliciclastic roch that have no obviolls genetic association with igneous activity.

China is the world's biggest producer of lead (56%) and zinc (37%), while Australia is the world’s largest exporter of both lead and zinc. Discovery in 1883 of the massive Pb–Zn–Ag deposits at Broken Hill, just east of the NSW–SA border, resulted in the establishment of a sea port at Port Pirie, followed by construction of a lead smelter and refinery in 1889.
