Complete the flow chart concentration of ore of aluminium
Answers
The Froth Floatation method is a method used for the concentration of metal ores.
2) It is used for the concentration of sulphide ores.
3) In this method, water is added to powdered ore.
4) To this, substances called collectors (such as pine oil ) are added so that the ore particles can be separated from the gangue particles.
5)The ore particles become wet by oil while the gangue particles become wet by water.
6) Air is blown in through a pipe and a rotating paddle agitates this mixture.
7) This forms froth.
8) The froth, being lighter, carries with it the ore particles and is separated from gangue.
9) So, the ore particles float above water. The froth is then skimmed off, leaving behind the gangue.
10) It is dried and metal is thus obtained.
