Nov 23, 2020 The agitation speed of the flotation cell was set at 700 rpm with a gas flowrate of 3 dm 3 /min. Flotation concentrates were collected by scraping the flotation froth using a scraper every 10 s. Four concentrates were collected at time intervals of 0.5 min, 1.5 min, 2 min, and 4 min. The pulp potential was monitored throughout the flotation.
