2019.7.29 It is clearly observed that optimum grade and recovery for copper was achieved at 4 min flotation time; however, for other valuable minerals, the ideal flotation time was ca 3.5 min. Increasing flotation time to 10 min (1st stage– 9 min+ 2nd stage −1 min), reduces copper concentrate grade to 2.3% from 12.28%.

2020.8.31 The froth layer thickness is crucial in flotation process, affecting both the recovery and the grade of the flotation concentrate. In general, the separation between the hydrophobic and the hydrophilic particles takes place in the pulp zone, but drainage in the froth zone is also important in controlling the selectivity of the flotation process.
