What is Talc ? Talc is the softest mineral (occupying place 1 in the Mohs hardness scale) known on our planet earth. It is a hydrated magnesium silicate [Talc chemical formula is Mg3Si4O10(OH)2 ]. Also known as Steatite. It is the main component of soapstone. Its crystals usually develop massive, leafy aggregates with laminar particles. Synonyms of Talc includes soapstone, steatite, silicates, Talcum powder etc Its silicate layers lie on

What is Calcite / Grounded Calcium carbonate (GCC) ? Calcium carbonate, or CaCO3, is one of the most useful and versatile materials known to man. It is extremely common and found throughout the world in sedimentary, metamorphic and igneous rocks. Some geologists consider it to be a “ubiquitous mineral” – one that is found everywhere. It comprises more than 4% of the earths crust and is found throughout the world.
What is Dolomite ? Dolomite is a common rock-forming mineral. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is rarely found in modern sedimentary environments but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of feet thick. Most
Kaolin is a white, soft, plastic clay mainly composed of fine-grained plate-like particles. Kaolin is formed when the anhydrous aluminium silicates which are found in feldspar rich rocks, like granite, are altered by weathering or hydrothermal processes. The process which converted the hard granite into the soft matrix found in kaolin pits is known as “kaolinisation”. The quartz and mica of the granite remain relatively unchanged whilst the feldspar is
What is Quartz ? Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is the most abundant mineral found at Earth’s surface and its unique properties make it one of the most useful natural substances. Quartz is the second most common mineral in the Earth’s continental crust. It is made up of a lattice of silica (SiO2) tetrahedra. Quartz goes by an array of
What is Barite / Barytes ? Barite or Barytes is chemically naturally occurring Barium Sulphate (BaSO4) with nodular particle structure. It receives its name from the Greek word “barys” which means “heavy.” This name is in response to barite’s high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical and manufacturing uses.
What is 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. Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements. Most of the products we use on a daily basis are made with feldspar:
What is Red Oxide ? Red oxide is chemically called iron oxide Red. It is red in color and Lusterless. Red Oxide powder is most widely occurring in nature. It is the basic mineral for steel plant. Red Oxide has tremendous application in building, construction, paint and many other industries. In India, good quality with high percentage of iron oxide is available in several regions. For paint, Ceramic, and building materials shade
What is Mica ? Mica is chemically a Potassium Aluminium silicate with a chemical formula [SiO2, Al2O3, K2O, Fe2O3, MgO, CaO, Hg2O] . It is described as faster dispersion, weather resistant, high degree insulation and aberration resistant. India is the single largest source of mica in the world. The British Geological Survey reported that as of 2005, Koderma district in Jharkhand state in India had the largest deposits of mica in the
What is Natural Silica / Silicon Dioxide ? Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is a dioxide of silicon with the chemical formula SiO2. It has been known since ancient times. Silica is most commonly found in nature as quartz, as well as in various living organisms, Silica is one of the most complex and most abundant families of materials, existing
