Reason for concentrating zinc ore by froth flotation during extraction

Update date: Apr 20

Zinc Blende does not contain a very high percentage of zinc and hence it needs to be concentrated. The best concentration method for zinc ore is known as froth flotation. Concentration of Ore: Froth Flotation Process. Froth Flotation process is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in
