Barite is the natural compound of the barium sulfate with the formula of 4BaSO, a sulfate which is also known as Heavy Spar. The name barite comes from the Greek word “barys” meaning “heavy” and is called so due to its particular and high heaviness. Its crystallization system is orthorhombic. The most important compounds containing barium are: Barite (4BaSO) and vitriol (3BaCO). Barite is found in more volumes than vitriol. In nature, barite is found in streak, la...

The name calcite comes from the Latin word “Calx” which means caustic lime. Calcite is crystallized in the trigonal system, askalnondryk class. It has large and clear crystals or in the form of granulation masses. Rombonder and skalnonder forms of calcite are more plentiful and have different and various twinning, too. The calcite structure is in the form of rombonder in which the calcium ions and the root (CO3)2- are in alternate order. In the root CO3, each carb...

Talc is the compound of water-contained magnesium silicate with the formula of 2(OH)10O4Si3Mg. Although the talc compound is usually very close to this general formula, some replacements take place. A tiny amount of Al and Ti can replace Si, a tiny amount of Mn, Fe and Al can replace Mg and a very tiny amount of Ca can replace Mg. When a large amount of Al replaces Mg this mineral is known as pyrophyllite. Talc is usually seen in green, white, grey and brown color...
