This magnetic separation method is suitable for metals that are attracted to a magnetised material and are separated from the non-magnetic particles, thereby enhancing the ore concentration. For this method, a magnetic separator is best suited to process iron ores like magnetite, chromite, and manganese, which are magnetic ores. Conclusion

Flotation of ore at a top-size of 3 mm, followed by gravity concentration of the flotation tailings, has been applied previously in South Africa to treat Witwatersrand gold ores resulting in the production of a 40% mass pull at an overall gold recovery of 98% (Lloyd, 1979). Coarse particle flotation of particle ranging from 3 to 5 mm is common ...

The ore is first crushed into fine pieces and then passed over a magnetic roller on a conveyor belt. The magnetic ore sticks to the belt while the gangue falls off. Froth Flotation Method: This method is primarily used to remove gangue from sulphide ores. The ore is ground into a powder and mixed with water to create a suspension.
