  • Selective flotation separation of spodumene from feldspar

    2020-6-5 · Micro-flotations of pure spodumene and feldspar were performed on an XFG flotation machine (spindle speed 1602 r/min) with a 40 mL small cell volume. The experimental steps were as follows 2 g pure minerals and 38 mL ultrapure water were first added to the flotation cell after stirring for 1 min dilute hydrochloric acid or sodium hydroxide then was added to pulp to adjust pH for 2 min.

    2018-11-27 · Rb and Cs can be used to depress the flotation of K-feldspar 13 . The adsorption and ion exchange of bivalent ions on the surface of feldspar were complex and the selective separation of albite from microcline was achieved by micro-flotation with CaCl2 and BaCl2 as the regulators and amine (G-TAP) as the collector 14 .
