Feldspar was officially given its name by Johan Gottschalk Wallerius in 1747. It is a contraction of the longer name fieldspar as some early specimens were found in fields. The term spar is a generic term used to refer to any non-metallic mineral with a vitreous (glassy) lustre that breaks on distinct flat surfaces.
Notes. Theoretically speaking, the term 'feldspar' refers to a family of minerals with a specific crystalline presence. However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 …

Feldspar forms in a variety of geological settings, from deep within the Earth's crust to the cooling lava of a volcano. This diversity in formation environments is a big reason why there are so many different types of feldspar. The range of colors seen in feldspar is due to trace elements and impurities that get mixed in during its formation.

Economic deposits of feldspar occur in a variety of rock types including anorthosite, aplite, nepheline syenite, and in pegmatites. Historically, feldspar in ia was mined for use in the ceramics industry, for abrasives, and for gemstones (amazonite) (Pegau, 1932). Prior to about 1907, feldspar was mined primarily as a by-product of mica ...
Regarding the granulometry, feldspar used in the ceramic industry must be smaller than 74 μm because its fluxing power is inversely proportional to its size [5]. This paper describes the tests in bench scale performed with samples from Marrom-Guaíba granite tailings in order to obtain a feldspar concentrate with chemical and granulometric ...

Orthoclase is the most common potassium feldspar, forming the majority of potassium feldspar found in felsic plutonic igneous rocks, some high temperature veins, and higher-grade metamorphic rocks. Sanidine has a less ordered crystal structure than orthoclase and is primarily found in volcanic igneous rocks where magmas cooled more rapidly and ...
Both feldspar and quartz in amine flotation and in the absence of HF need not be floated at pH less than 4. However, in the presence of HF feldspar is floated at pH 2–3 while quartz does not float. Feldspar was floated using tallow amine acetate at a pH of 2–3 (Abdel-Khalek et al., 1994; Sekulic et al., 2004), with a pulp density of 25%.
