1. froth floatation seperation
2. magnetic seperation
the method in which pine oil is used is "froth floatation"
method:-
the ore which is to be concentrated is taken in a container and is mixed with water and pine oil. air is blown with pressure which creates froth
the ore particles have different wetting properties than the impurities
the ore particles get stuck to the oil and rise up to the surface whereas the gangue impurities get stuck to the water and settle down.
the froth can be collected seperately and the required ore can be obtained by suitable processes
this method is usually done to sulphide ores.
