Celestite

Celestite also known as Celestine (SrSO4) is a naturally occurring form of strontium sulfate. It is very similar to barite (barium sulfate), but less common. Celestite occurs in sedimentary rock formations, especially in dolomite and dolomitic limestone. Celestite is mined industrially as a source of strontium. Celestite also forms with other colorful minerals, making very nice combinations. Blue Celestite with bright yellow sulfur is one of the most famous colorful combinations of minerals. The ideal composition of Celestite is: SrO 56.42 % SO3 43.58 %. Iran has several Celestite mines and great potentiality for exporting. So Iran is one of the best Celestite suppliers of Middle East. Marjan Mineral Company has a great ability to provide all necessary things for exporting. Read More . . .

Celestite Occurrence

Celestine occurs as crystals, and also in compact massive and fibrous forms. It is mostly found in sedimentary rocks, often associated with the minerals gypsum, anhydrite, and halite. The mineral is found worldwide, usually in small quantities. Pale blue crystal specimens are found in Madagascar. The skeletons of the protozoan Acantharea are made of celestine, unlike those of other radiolarians which are made of silica. In carbonate marine sediments, burial dissolution is a recognised mechanism of celestine precipitation.

Celestite Usages

Almost all Celestite (99%) is used in the production of strontium carbonate. There are four main uses for Strontium Carbonate.

• Glass: SrCO3 (Strontianite) is used in faceplate glass in TV and CRT glass to block X-rays and to improve glass quality.
• Ceramic ferrite magnets: SrCO3 is mixed with iron oxide and processed to form strontium hexaferrite for use in permanent ceramic magnets. Read More . . .
