Dolomite chips, 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.It 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 rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were post-depositionally altered by magnesium-rich pore water to form dolomite.It is a double carbonate of calcium and magnesium (CaCO3, MgCO3). It is one of the important raw materials used in the iron and steel, ferro-alloys, glass, alloy steels, fertilizer industry, etc.

Quartz grain, 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) tetrahedral.It goes by an array of different names. The most important distinction between types of quartz is that of macro crystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification). Quartz is also known as a ubiquitous mineral with an enormous number of uses.Quartz Processing (Silicon dioxide, SiO2) At a share of approx. 12 %, quartz ranks second behind feldspar as the most common mineral of the lithosphere, either in the form of solid rock or eroded sand. After being processed to quartz sand < 600 μm, the quartz is used in the manufacture of glass; for special paints (road building); in foundries as molding sand; in adhesives for the ceramics industry; in sand blasting equipment; for sanding sports stadiums; etc. Even finer in the < 80 μm range with a steep particle size distribution is found in ceramic base compounds, and at a fineness of < 20 μm in glazes.It has a hardness of 7 on the Mohs’ Scale which makes it very durable.Quartz is silicon dioxide [chemical formula is (SiO2)].
