wolframite flotation

Research on flotation mechanism of wolframite activated by

Nov 15, 2020· Wolframite and scheelite are two critical sources of tungsten. At present, flotation is an efficient mineral processing method to recover tungsten ores of low grade and fine grain. Fatty acid is usually used as a collector of scheelite but has weak effects on wolframite flotation.

Apr 13, 2020· The PH value of the wolframite flotation with oleic acid is similar to that of scheelite, and sodium carbonate is used as the adjusting agent. The flotation of wolframite with phenylarsinic acid and phosphonic acid is carried out in acidic medium, and the regulator used is sulfuric acid or hydrochloric acid. Commonly used lead nitrate as activator.

Study on the activation mechanism of lead ions in

Sep 01, 2019· The wolframite flotation recovery as a function of BHA concentration with and without Pb(II) at pH 8.5 is shown in Fig. 4. The recovery gradually increased with the increase in BHA concentration and maintained constant when BHA concentration was above 5.8 × 10 −4 mol/L. In this case, only 30% of the wolframite were recovered.
