Flake material such as graphite, molybdenite, and mica has been separated successfully from quartz, feldspar, or other gangue materials. The electrostatic shape separator combines sizing, shape separation, and separation according to difference in electrical conductivity of particles.
An alternative process which exhibited effective separation of quartz and feldspar while recycling the tailwater from the flotation was proposed. ... [49][50] [51], entailing much stronger ...
At pH 6.50, with 8 mg/L SDA, effectively recovering malachite from quartz was achieved by reverse flotation, in which 92.71% of malachite was recovered and 91.91% of quartz was removed, coupled ...
Tests conducted on binary mixtures of K-feldspar/Na-feldspar, K-feldspar/quartz, and Na-feldspar/quartz showed that it is possible to achieve satisfactory results in the separation of these species, by triboelectrical charging of the material, preheated to temperatures above 100°C, using a free fall chamber.
Effects of Ca(II), Mg(II), Cu(II), and Fe(III) on the flotation separation of spodumene from feldspar and quartz were investigated.. Ca(II), Mg(II), and Cu(II) selectively improved the flotation of spodumene, whereas Fe(III) showed strong activation ability but low selectivity toward spodumene.. At a pH of approximately 7, Ca(II) and …
