Separation Feldspar Quartz

Developing Effective Separation of Feldspar and Quartz ...

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [].However, there is a large amount of chemical activator (HF or NaF) in the flotation system, as ...

1. Difficulties in separation of feldspar and quartz ...

Quartz and feldspar are both silicate minerals with a frame-like structure, which are similar in physical and chemical properties, such as non-magnetic and close in density. Currently, flotation is mainly used for separation. Although the hydrofluoric acid method can separate quartz and feldspar better, because of the serious pollution of the environment and equipment by HF, the current ...
