    Jan 17, 2022 As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K. The impure zinc obtained after reduction is purified by electrolysis

    flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface

    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 water. The main ingredients of the froth flotation are the Collectors and Froth Stabilizers

    In some sulphide ores of copper, zinc and lead, the concentration is brought by the froth flotation process.In this method, the advantage is taken of the preferential wetting of the ore by an oil. The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil. Collectors (e.g., pine oils, fatty acids, xanthates, etc.) enhance the non-wettability of the mineral
