Which Of The Ores Are Concerned By Froth Flotation Process

Answer. Sulphide ores are concentrated by froth- flotation process. Only sulphide ores are concentrated by this method because pine oil selectively wets the sulphide ore and hence brings it to the froth. Answer verified by Toppr. 18 Views

    Explaining the Process of Froth Flotation

    Mar 27, 2016 The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which are floated are sulphides of

    Apr 17, 2019 Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation
