Feldspar Chemical Composition

FEldspar is a mineral that accounts for up to 60% of the Earth''s crust. Feldspar is divided into two types, both of which are composed of silica and aluminium. In 2010, about 20 million tonnes of feldspar were produced, mainly by three countries: Italy (4.7 million tonnes), Turkey (4.5 million tonnes), and China (4.5 million tonnes) (2 Mt).

Fluorspar

Fluorspar (or, to use its mineral name, fluorite) is calcium fluoride (CaF2). While most commonly used to refer to the mineral when mined from the Earth''s crust, fluorspar also refers to the calcium fluoride produced as a by-product in various chemical processes, such as the production of phosphoric acid, refining petroleum or enriching uranium for […]

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. The term feldspar encompasses a whole range of materials.

Flourspar / Fluorite

Fluorspar is used as fluxing agent which increases the fluidity of steel. Two Types of Grade :- 1. Acid Grade and . 2. Metallurgical Grade. Fluorspar is recognised as a strategic mineral by the United States of America and the European Union and is mined for the production of calcium fluoride (CaF2).
