Reexamination of common extraction and purification ...

quartz samples contained small amounts of feldspars (3– 10%), indicating that neither density separation nor magnetic separation can fully remove all feldspars, and that HF etching is essential. SEM/EDS mapping also showed that the alkali feldspar extracts contained some quartz grains (˘5%). Roughly15% Narich grains were observed within ...

Selective Flotation Separation of Feldspar in Non Fluoride ...

Since the inception of the feldspar flotation process using hydrofluoric acid by O’Meara the process has achieved a great commercial success. 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.

purified quartz contains no measurable feldspar, concentrated (4048%) hydrofluoric acid (HF) is typically used to dissolve the remaining feldspars and at the same time etch the quartz. An alternative method for removing heavy minerals and most feldspars is magnetic separation. Whilst this is not a new procedure (Rosenblum, 1958), the use of
