(PDF) BULK FLOTATION OF COMPLEX COPPER ORE
The difference in volume of the water after filling the flask with the ore specimen was used to solve the density of the ore using this equation: D= Where m is the mass of the ore and v is displaced water volume. 3.2 Bulk Flotation A one kilogram ore, passing -200 mesh was fed to the flotation machine for the bulk flotation of copper and zinc.
