  • Improving flotation separation of apatite from dolomite

    Sep 01, 2020· For each experiment, 2 g of either single mineral samples or mixed mineral samples (1 g apatite and 1 g dolomite) was added into a 30 mL of flotation cell containing the desired amounts of deionized water. The prepared suspension was stirred for 1 min, and its pH was regulated into the desired values using dilute HCl and NaOH solution.
