Principles And Practice Of Sulphide Mineral Flotation

Mineral processing Flotation collectors (promoters) are used extensively for the flotation of sulfide minerals including copper gold lead zinc nickel iron and many others such as lithium These products provide improved performance and higher selectivity than traditional sulfide collectors and better overall metallurgical.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.
