  • Flotation of Fine Gold Particles by the Assistance of Coal ...

    The studies showed that petroleum oils are more effective than vegetable oils in oil agglomeration of Kozlu coal and coaloil assisted gold flotation. Gold recovery can be increased using a higher amount of agglomerates in the process; however, gold grade of the flotation concentrates is reduced significantly.
