Dolomite is an anhydrous carbonate mineral. It is a double carbonate of calcium and magnesium (CaCO3.MgCO3). It is one of the important raw materials used in production of iron and steel. Dolomite contains theoretically 54.35 % of CaCO3 and 45.65 % of MgCO3 or 30.41 % of CaO, 21.86 % of MgO, and 47.73 % of CO2.

Dolomite is a calcium magnesium carbonate mineral which has many characteristics similar to calcite. In places where access to limestone is not available or more costly, dolomites are used in its place for the basic materials from which most building stone and a significant percentage of crushed stone are produced.

DOLOMITE MINING. An undated photo shows the dolomite mining plant in Barangay Pugalo, Alcoy town in Cebu province. Alcoy Mayor Michael Angelo Sestoso on Wednesday (Sept. 23, 2020) said the residents of his town are very happy that they became a major contributor to the Manila Bay nourishment project using their dolomite.
Mining is the process of digging into the earth to extract naturally occurring minerals. It can be categorized as : surface mining, underground mining, and in situ mining. Surface mining is used to excavate ores at or close to the earth's surface ; underground and in situ mining both remove minerals from deeper deposits.
In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel. In agriculture, dolomite is used as a soil conditioner and as a feed additive for livestock. Dolomite is used in the production of glass and ceramics.

LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone, or by direct precipitation.
AM2+(CO3)2. A = Ca, Ba. M = Fe 2+, Mg, Mn, Zn. Name: After the principal species in the group. Members of this group have a crystal structure similar to that of calcite. In dolomite, alternate Ca positions are occupied by Mg, these becoming structurally non-equivalent and the crystal point symmetry being lowered from 3 2/m to 3.
making lime (CaO) that is used to . treat soils, purify water, and smelt copper. Lime has many additional uses in the chemical industries. Dolomites are commonly less suitable . than other industrial limestones for most applications. Most dolomite that is mined is simply crushed and sieved for use as aggregate in concrete or asphalt.
Dolomite is used to describe both a mineral and a rock. The mineral is the pure form with a defined crystal structure and chemical formula, whereas dolomite rock is composed chiefly of the mineral Dolomite, but also contains impurities such as Calcite, Quartz, and feldspar.

The limestones and dolomites are used as fertilizer, soil conditioners, and correcters for soil acidity. The major prerequisite for the limestone or the dolomite used as agricultural stone is that it have a high percentage of calcium or magnesium available for improving the soil. Limestone dust is used as a filler in road asphalt surface mixtures.

Mining and processing domestic magnesium ores was expanded in the early 1940's to provide material for the production of chemicals and magnesium metal as well as refractories. Also in the early 1940's, magnesium chloride, recovered from seawater, was used in large quantities to produce magnesium metal in plants in Freeport and Velasco, TX.
Phosphorus as phosphate and nitrogen as ammonium or nitrate are the main nutrients in wastewaters and agricultural sludges. They runoff easily to waterways and cause eutrophication in water bodies. However, ammonium and phosphate could be precipitated simultaneously and used as recycled nutrients. In this research, dolomite calcined at 650 °C, 750 °C, or 950 °C and commercial …
