Sandstone - Minerals Education Coalition
Sandstone. Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

With this sand the pH rose somewhat due to carbonate in the pulp so that 5 cc of acid instead of 4 cc was used. The feldspar was floated in stages using 0.1 pound of Armac 12-D per ton and about 0.05 pound of frother B-23. The sands from near Wichita and Concordia required only three stages to remove most of the feldspar.

Relevant Problems of Quartz Extraction Technology
Quartz sand xenoclasts contain hematite, limonite, biotite and other weak magnetic separation minerals as well as secondary cast iron in the crushing process. Usually, strong magnetic separation equipment is used to remove these impurities. If there is magnetite impurity in quartz sand, it can be removed by weak magnetic separation equipment.

What Is Silica Sand & How Is It Different From Regular Sand?
Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...

Feldspars and mica are also objectionable. Generally, iron content must be reduced to 0.030% Fe2O3 or less. & Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than 0.03% Fe2O3.

Feldspar - Wikipedia
Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Feldspar - an overview | ScienceDirect Topics
Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
