Minerals are all around you They are used to make your house your computer even the buttons on your jeans But where do minerals come from? There are many types of minerals and they do not all form in the same way Some minerals form when salt water on Earth's surface evaporat Others form

Potassium feldspar (K spar) has technical advantages over sodium feldspar (Na spar) as it forms a melt of high viscosity that decreases only slightly with increased temperature thereby making ceramics stronger and more refractory K spars are mainly used in electrical porcelain applications and

The name feldspar derives from the German Feldspat a compound of the words Feld "field" and Spat meaning "a rock that does not contain ore" The change from Spat to spar was influenced by the English word spar meaning a non opaque mineral with good cleavage Feldspathic refers to

It is a white or gray clay mineral which is the chief constituent of kaolin clay The precise chemical nature of the kaolin will be defined by the nature of the original feldspar that is whether it was aluminum sodium calcium or potassium rich as these are the ions that will have been dissolved in solution

The feldspar group is a fairly large group with nearly 20 members recognized but only nine are well known and common Those few however make up the greatest percentage of minerals found in the Earth's crust The following are some of the more common feldspar minerals

Sometimes sand contains new minerals or mineral aggregates that were non existent in the source rocks Notable example is a clay mineral glauconite which forms in marine sand and gives distinctive dark green color to many sand sampl In some instances glauconite in sand may come from disintegrated glauconitic sandstone nearby but eventually it is of marine origin anyway

In order to improve the purity or the whiteness of feldspar flotation [3 4 5] and magnetic separation are typically used to remove associated minerals (such as quartz and dark colored minerals rich in iron) from feldspar [6 7 8] Traditionally there are two main flotation separation processes to remove quartz from feldspar

Feldspar is by far the most abundant group of minerals in the earth's crust forming about 60% of terrestrial rocks Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars Feldspars are primarily used in industrial applications for their alumina and alkali content

Feldspar Feldspar Identification of specific feldspars Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure) which is manifested by parallel lines on certain cleavage surfaces whereas grains of alkali feldspars do not This criterion is not however absolute; some plagioclase
