potash feldspar

Potash Feldspar :

Most of this feldspar is crushed into fine granules or powders and then consumed in factories that produce plate glass, ceramic tile, fiberglass insulation, paints, plastics, pottery, container glass and other products. Feldspar is the name given to a group of naturally occurring alumino-silicate minerals containing varying amounts of potassium, sodium, calcium and/or lithium. The feldspar group of minerals is by far the most abundant group of minerals in the Earth’s crust, making up about 50% of all rocks. Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on their feldspar content.
