Investigation reveals enhanced apatite flotation from reduced Ca2+ and Mg2+ ions by pH regulators, suggesting optimal conditions for mineral processing.
Key Points
Apatite flotation performance improved by regulating pH levels using specific agents.
Optimal ratios of CO32- to HCO3- and OH- lead to over 90% removal of Ca2+ and Mg2+.
The study highlights the importance of controlling pH for effective mineral flotation.
Excessive Ca2+ and Mg2+ can lower concentrate grade and increase collector consumption.
