Question

Name the process used for the enrichment of sulphide ore.

Answer 1

1. Froth flotation method is used for enrichment of ore having sulphide content in it.
2. The term flotation means to separate mineral particles according to the difference in their physical and chemical properties.
3. As sulphide minerals have high floatability, this process is especially used for sulphide minerals.
4. In this method of froth flotation, water and fine powder of the ore are filled in a big vessel.
5. After this substances like pine, or turpentine oil is poured into it. By doing so the sulphides of metal get wet and stick to it, while clay and particles of sand do not get wet.
