remove feldspar from sand - hbdepopulier. These Processes Can Remove Impurities from . 02 Potassium feldspar flotation separation. When the iron-containing impurities in potassium feldspar are pyrite, mica or in the form of iron-containing alkali metal silicate minerals such as garnet, tourmaline and hornblende, the flotation method is mostly used to remove the impurities.

Sandstone - Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.

If feldspathic sand is the raw material, no size reduction may be required. Also, if little or no mica is present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking.
