    [Solved] Froth floatation method is mostly used for the

    The process is commonly used for sulphide ores. This is because pine oil used in the process selectively wets the sulphide ore and hence brings it to the froth. Froth flotation can primarily be done under two common techniques: Direct floatation technique - The mineral sticks to the air bubble and the remaining gangue settles down at the bottom

    Extraction of Zinc: Froth Floatation Process, Roasting

    Nov 30, 2021 The principal ore of zinc used for its extraction is Zinc blend ( Z n S). 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

    Froth floatation is based on the principle of the difference in the wetting properties of the ore and gangue particles with the water and oil. This method is used for those metals whose ore gets preferably wet by the oil and the gangue by the water. The sulphide ores get preferably wet by the oil and the gangue with the water

    Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the
