Feldspar - Feldspar - Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Aug 10, 2019· For general purposes, like picking granite for a countertop, it doesn't matter what type of feldspar is in a rock. For geological purposes, feldspars are quite important. For rockhounds without laboratories, it's enough to be able to tell the two main types of feldspar, plagioclase (PLADGE-yo-clays) feldspar and alkali feldspar.

Mining Matters is a charitable organization dedicated to bringing knowledge and awareness about Canada's geology and mineral resources to students, educators and the public. The organization provides current information about rocks, minerals, metals, mining and the diverse career opportunities available in the minerals industry.

11.27 Feldspar Processing 11.27.1 General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).

Nepheline syenite is a holocrystalline plutonic rock that consists largely of nepheline and alkali feldspar.The rocks are mostly pale colored, grey or pink, and in general appearance they are not unlike granites, but dark green varieties are also known. Phonolite is the fine-grained extrusive equivalent.

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 is the most common mineral on Earth, constituting approximately 60% of the crust.It forms directly from cooling magma and is a major component of granite and most other igneous rocks.. The term feldspar actually covers a whole family of minerals, all of which consist of a framework of aluminum, oxygen, and silicon atoms plus an additive, usually potassium, sodium, or calcium.

Feldspar had been discarded in the process of mining mica until William Dibbell sent a premium quality product to the Ohio company Golding and Sons around 1910. In earth sciences and archaeology, feldspars are used for K-Ar dating, argon-argon dating, and luminescence dating.
