Studies on the Flotation of Mixed Oxide-Sulphide Ores of Copper from Malanjkhand Deposit India.

Bench scale experiments on the benefition of a mixed oxide-sulphide ore of copper from Malanjkhand deposit of Hindusthan Copper Limited, India conducted with certain modifications in collector systems within the limits of existing plant operating conditions yielded better metallurgical results. Sodium isopropyl xanthate (IPX) and sodium diethyldithiocarbamate (DTC) were tried as collectors along with modifiers, such, as, sodium silicate,Magnafloc guargum, and were optimised. All the variables such as concentration, pH of the slurry were stematically studied. Improved metallurgical results were obtained with isopropyl xanthate in combination with sodium silicate guargum at pH 9.0. The results were also equally good with dithiocarbamate,a chemisorbing collector
