On Ni Froth Flotation From Bangladesh

The flotation experiments were performed in a 0.5 L mineral separator (MS) type laboratory flotation cell to upgrade recoveries of Cu and Ni (bulk flotation) from mine tailing. In flotation tests, an appropriate weight of the mine tailing sample was poured into 500 mL of water to prepare slurry/feed with different pulp densities from 10% to 25%

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 5-3Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while
