The muscovite in this study is a concentrate product of flotation, and the particle size is less than mm. Xray diffraction analysis shows that the raw material is primarily muscovite and quartz. All samples are heated in a muffle furnace at temperatures ranging from 550 to 950 °C for h.Get Price
biotite floatation process
Flotation of mica minerals and selectivity between . The biotite grade and recovery are found to be around 30 and 20 respectively. A good selectivity between muscovite and siliceous gangue is obtained. A final product containing 95 muscovite with an overall recovery of 75 is obtained when the flotation concentrate is .Get Price
Froth flotation of mixed feldspar
Froth flotation of mixed feldspar ... quartz, micas (muscovite and biotite) and small amount of ironbearing minerals. However, most of mixed feldspars cannot be directly used as raw materials for high grade ceramics. In order to upgrade mixed feldspars, froth flotation (Rau, 1985) could be applied to separate feldspar from those micas and ironbearing minerals, and quartz respectively. The ...Get Price
Influence of metal ions on muscovite and calcite flotation ...
Mar 05, 2019 · It could be seen that the muscovite did not float with sodium oleate as collector and the introduction of Ca 2+ had no influence on its flotation performance. But the introduction of Al 3+ and Fe 3+ significantly changed the flotation behavior of muscovite. Specifically, the addition of Al 3+ allowed the recovery of muscovite to be substantially increased by 20%–60% at pH –Get Price
