Efficient Recovery of Feldspar, Quartz, and Kaolin from …
Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process …

Flotation separation of feldspar from quartz using sodium
The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na2SiF6; SF) as a selective depressant was investigated. Moreover, the influence mechanism of SF on the selective …
