Study on Flotation Mechanism of Separation of Potassium ...

Potassium feldspar and quartz are all silicate minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and cation mixed collector was studied in the paper.

Selective flotation separation of spodumene from feldspar ...

The flotation separation of spodumene from other complex aluminosilicate minerals such as feldspar and mica, is problematic, due to their same active Al site for interaction with anionic collectors (Rai et al., 2011). In practice, the general method to accomplish effective spodumene flotation is to add amount of depressants associated with ...

Developing Effective Separation of Feldspar and Quartz ...

In order to improve the purity or the whiteness of feldspar, flotation [3,4,5] and magnetic separation are typically used to remove associated minerals (such as quartz, and dark-colored minerals rich in iron) from feldspar [6,7,8]. Traditionally, there are two main flotation separation processes to remove quartz from feldspar.
