Quartz and feldspar are both silicate minerals with a framelike structure, which are similar in physical and chemical properties, such as nonmagnetic 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 ...

Jul 30, 2020· Besides heavy minerals and magnetic impurities, there are also a variety of mica minerals contains in quartz sand. It is impossible to remove the impurities completely only by the gravity separation and magnetic separation. Furthermore, quartz sand also contains a certain amount of feldspar minerals with a similar gravity to that of quartz.
In the conventional flotation separation of feldsparquartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector. The bulk of amine collectors used in current feldspar operations are applied as the watersoluble acetates of the freebase amines.
