  • Kinetics of Flotation of Copper Tailing from Benambra

    A variable quantity of copper mineral collector according to the test in question was added, then conditioned the pulp for 2 minutes. The froth was removed by hand, scraping the full length of the cell at constant depth every 10 seconds. No frother is required for this copper tailing flotation.

    Separating minerals in a froth floatation cell is a particularly corrosive, difficult to maintain operation. While the mixture of slurry, surfactant, water, air and froth in a given process varies, the ultimate effect on the slowly rotating rake and its related components is too often the same failed seals and bearings, plus unplanned downtime and lost productivity.
