Uses of Dolomite. Dolomite and limestone are used in similar ways. They are crushed and used as an aggregate in construction projects. They are kilnfired in the manufacture of cement. They are cut into blocks and slabs for use as a dimension stone. They are calcined to produce lime. In some of these uses, dolomite is preferred.
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
LIMESTONE AND DOLOMITE IN THE BIRMING HAM DISTRICT, ALABAMA. By CHARLES BUTTS. INTRODUCTION. Both limestone and dolomite are important from an economic standpoint in the Birmingham district. Limestone is used for lime and cement, and both limestone and dolomite are extensively utilized as flux in iron smelting.
Dolomitic lime and clacium carbonate are great when used with calsium sulphate, here in brasil we used to eliminate Al but we saw that besides giving a better ratio of calcium and Mg it also can take Ca to lower levels since de dolomitic lime and CaCO3 do not move easely in the :if you use CaSO4 with potasim fertilizers insted of CaCo3 you can move some K to lowers levels of the soil.
· Pig iron must therefore be desulphurised and decarburised! Desulfurization. The refining of pig iron into steel is carried out in liquid form. For this purpose, the pig iron produced in the ironworks is first collected in large mixing containers (called pig iron mixers) with a capacity of up to 1800 tons.
Iron and Steel Production in Birmingham | Encyclopedia,, Iron and Steel Production in, each controlling substantial deposits of iron ore, coal, limestone and dolomite,, most of the pig iron produced at the Thomas .Pig iron, An intermediate product of puddling is known as refined pig iron, finers metal, or refined iron Pig iron can also be used to produce gray ironTITANIUM IN THE .
Iron is produced in blast furnaces by the reduction of ironbearing materials with a hot gas. The large, refractorylined blast furnace is charged through its top with iron ore pellets, sinter, flux (limestone and dolomite), and coke, which provides fuel and forms a reducing atmosphere in the furnace.
· Pig iron is the product of smelting iron ore (also ilmenite) with a highcarbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces. How was the Bessemer invented?
The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Dolomite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process
· Uses for limestone have a wide range but is commonly used to adjust the pH in soil. Ag Lime is proven to be a simple and costeffective way to counter the harsh conditions created by rising acidity. Appliions of Ag Lime are a reliable way to keep your soil healthy and highyielding.
Dolomite long has been used as a source of calcium and magnesium for animal feeds. Dolomite now is available in a number of dosage forms including tablets and chewable wafers, to be taken as dietary supplements. In animal models, minerals from dolomite are well absorbed. Research reveals no animal or clinical data regarding the use of dolomite ...

Charcoal and anthracite are also used as fuel and reductant. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces .
PigIron Production The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. Coke is the hard, porous residue left after the destructive distillation of coal. Used as a reducing agent in the smelting of pig iron and as a fuel, coke is blackishgray and has a metallic luster. It is composed largely of carbon ...
Limestone Uses. It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime). Is overwhelmed to be used as aggregate—the strong base for many roads as well as in asphalt concrete.
The limestone and dolomite are used for purifiion purposes. In most of the iron and steelproducing centers, there is no dearth of supply of limestone and dolomite. ADVERTISEMENTS: Capital and market are also important factors in localisation of industries, including iron .
