sulphide ore is concentrated by froth flotation process

Froth-flotation process is used to concentrate sulphide ores.

Froth floatation process is especially suitable for sulphide ores. It is based on the difference in wetting characters of the ore and gangue with water and oil. Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Sulphide ores of metals are usually concentrated by froth

The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.

rotating paddle agitates the mixture and draws air into it. As a result, froth is formed which carries the mineral particles. The froth is light and is skimmed off. It is then dried for recovery of the ore particles. The gangue material is wetted by water and settles at the bottom. 7)Sometimes, it is possible to separate two sulphide ores by

Froth Flotation Process Detailed Explanation With

Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.
