Vedclass · Answer

(A) The froth floatation process is used for the concentration (purification) of ores,especially sulphide ores.It is based on the principle of the difference in wetting properties of gangue and ore particles in water and a frothing agent (ore particles are wetted by oil,while gangue particles are wetted by water).Statement $I$ is correct as it is used for sulphide ores.Statement $II$ is incorrect because roasting is a separate metallurgical process.Statement $III$ is incorrect because relative density is the basis for hydraulic washing,not froth floatation.Statement $IV$ is correct as it describes the fundamental principle of the process.Therefore,$I$ and $IV$ are correct.
