SELECTIVE SEPARATION OF Na- AND K-FELDSPAR FROM

2016-4-1  The possibility of recovering mica, feldspar and quartz from granite quarry operations in Missouri, Minnesota and Wisconsin showed that recovery of feldspar and quartz concentrates is possible. The recovery of feldspar and glass sand from South Carolina waste granite fines using HF-amine method showed the possibility of recovering high-grade feldspar and quartz products from South Carolina waste granite fines when the froth flotation was supplemented by magnetic separation. The suitability of weathered granitic rocks for the raw material of feldspar and silica sand indicated that granite is more useful than granodiorite as a raw material, because the former is rich in quartz and potash feldspar. Good results of feldspar flotation was obtained for granite compared to granodiorite. They also explained that a coarser grain is more difficult to float than a finer one, and K-feldspar

Feldspar vs Mica What's the difference? WikiDiff

As nouns the difference between feldspar and mica is that feldspar is (mineral) any of a large group of rock-forming minerals that, together, make up about 60% of the earth's outer crust the feldspars are all aluminum silicates of the alkali metals sodium, potassium, calcium and barium feldspars are the principal constituents of igneous and plutonic rocks while mica is any of a group of hydrous aluminosilicate minerals characterized by highly perfect cleavage, so that they readily separate
