As it is imperative that the purified quartz contains no measurable feldspar, concentrated (40-48%) hydrofluoric acid (HF) is typically used to dissolve the remaining feldspars and at the same time etch the quartz.

Most silicate minerals dissolve faster than quartz in dilute HF and can be etched away to leave a very pure quartz residue. Some quartz is lost - usually ~10% of coarse-grained fractions (500-850 ∝m) and up to 20-30% of fine-grained fractionsUse of magnetic separation for purifying quartz for,,Subsequent heavy liquid separation at a density of 2.7 g/cm3 showed that only several grains of heavy mineral remained, mostly apatite and fluorite. Zircon, a luminescent mineral, is very rare in sediments and is highly unlikely to remain after magnetic separation. Magnetic separation is a common physical method used for separating minerals with different magnetic properties. In industry it is,Heavy Liquid Separation: To separate out the quartz, the,,Heavy Liquid Separation: To separate out the quartz, the heavy liquid "LST" is used. The density of the liquid is higher than that of quartz. As drops of water are added to the LST the quartz begins to fall due to the density change of the liquid!
