Notes On Concentration Of Ores Cbse Class 12 Chemistry

Metals can be concentrated from their ores using any of these methods - hydraulic washing, magnetic separation, froth floatation or leaching. The choice of the technique used for extraction depends upon the differences in the physical properties of the compound of the metal present and that of the gangue.

Describe Froth Floatation Process For Concentration Of

Froth floatation process 1 Froth floatation process is based on the principle of difference in the wetting properties. of the ore and gangue particles with water and oil. 2It is used for the extraction of those metals in which the ore particles are preferentially. wetted by oil and gangue by water.

A method of concentrating phosphate minerals from their ores comprising subjecting the ore as an aqueous pulp to a first froth flotation treatment in the presence of an anionic collector under conditions sufficient to produce a first froth overflow product of rougher phosphate concentrate and a first underflow product of siliceous material subjecting the first froth ...

Froth Flotation Method Is Used For Concentration Of

Froth Floatation Process Fun Science This method is used for concentration of sulphide ores of copper, lead and zinc.In this method, powdered ore is put in a tank full of water.And then, some pine oil is added to it.In the tank the particles of sulphide ore are wetted by pine oil whereas the gangue particles.

Froth Floatation Process Used For The Concentration Of

Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.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.

Froth Flotation In Concentration Of Copper Ore

Flotation Of Nickel. Abstract-froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. one of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. this therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as.
