froth flotation method for sulphide oresiron ore processing methods

Froth Flotation Method For Sulphide Oresiron Ore Processing Methods

metallurgy - purification of ores,(ii) froth flotation process . this method is especially suitable for sulphide ores like zinc blende (zns), and copper pyrites (cufes 2). this process is based on the fact that the sulphide ore particles are only moistened by oil; while those of oxide, and gangue particles are moistened only by water..floatation - slideshare,oil and froth float on the surface along with the sulphide ore. the gangue particles being insoluble in oil remain at the bottom of the water tank. the froth is removed and allowed to settle down. this is called the froth-floating process. this process is used for sulphide ores of cu, pb and zn 10 11..
