4. Fertilizer Industry: Dolomite for use in fertilizer industry must have CaCO3 +MgCO3 90% (min) and Si02 5% (max). Inferior grade dolomitic limestone of 15-20% MgO can be used as soil conditioner. Ground dolomite, 50% of which must be 100 BS mesh size be considered suitable as a soil conditioner if it is applied at the rate fo 2-3 ton per acre.

Dolomitic Limestone. Dolomitic limestone is a rock composed mainly of calcite, but some of that calcite has been altered to dolomite. Dolomite is thought to form when the calcite (CaCO 3) in carbonate sediments or in limestone is modified by magnesium-rich groundwater.

Integrated Data Enhance Dolomite Mapping. Carbonate sedimentary rocks that have been dolomitized and laterally sealed by tight undolomitized limestone frequently are seen to produce hydrocarbons. The process of dolomitization increases the crystal size and pore size, and thus enhances its porosity and permeability.

Dolomite is a double Carbonate of Calcium and Magnesium. This means that it loses nearly 50% of its mass upon ignition by way releasing Carbon Dioxide. Subsequently, Iron and Steel manufacturing plants use Dolomite Powder as a fluxing agent because of its Oxidising property. Additionally, calcined and sintered Dolomite is used as refractory ...

May 08, 2013 Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron.

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone in the United States …

Limestone is an occurring type of sedimentary carbonate rock found on Earth’s surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.
