The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in the water.
