The mineral particles become wet by oil

(C) . This principle is valid for magnetic separation.$B$. This principle is valid for gravity separation.$D$. It is possible to separate two sulphide ores by adjusting the proportion of oil to water or by using depressants.$C$. In the froth flotation process,the mineral particles are preferentially wetted by oil,while the gangue particles are wetted by water. Thus,option $C$ is the correct statement.
