Technical processes for separating minerals by flotation

Technical processes for separating minerals by flotation

Technical processes for separating minerals by flotation 1 Until about 1919 the practice of flotation was conducted with much secrecy, and was on a semi-empirical basis. Since then the literature has become voluminous and in recent years the scientific principles underlying it have been fairly well elucidated. A long paper by Sulman (Trans. Inst. Min. and Met., 29,44-204 (1919)) gave the first ...

This process of Froth Flotation became the hallmark of Mineral Separation Ltd and constituted a major revolution in minerals technology. In 1905, this process was adopted at Broken Hill and effectively solved the problem of recovering the precious minerals from the tailing dumps. All was not solved, however, for two problems persisted.

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.
