Q1 discribe the froth floatation process.Q2 discribe electromagnetic separation
​

Answer 1

1. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
2. A process of removing magnetic materials from relatively nonmagnetic materials, using electromagnets which travel along a conveyor, over a drum, or into a revolving screen. See Also: electrostatic separator, tramp iron. Ref: Nelson
