The limestone is added to the iron ore burden of the blast furnace in the amount of ~117kg per tonne of "hot metal" (steelmaker's slang for the liquid iron produced by the blast furnace). This produces the slag of 181kg per tonne of hot metal which contains most of the impurities: 38% SiO2, 36% CaO, 14% MgO, 9% Al2O3, plus minor amounts of other impurities (mostly sulfur).

All varieties in the CalciteDolomite horizontal column are possible here. Carbon Humus: Yields carbonaceous derivatives Sapropel: Yields bituminous derivatives: Peat: dark semicarbonized plant remains

Karnataka is also endowed with the green stone belt with valuable mineral resources such as gold, silver, copper, ironore, manganese, limestone, dolomite, asbestos, bauxite, chromite, kaolin and granite rock. The main minerals found in Karnataka are listed below:

Commodity: Limestone, a sedimentary rock that is dominantly composed of the calciumbearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calciummagnesium carbonate (formula CaMg(CO3)2).

Mar 05, 2018· The coke is a source of carbon monoxide which will reduce the iron oxide in the ore to iron and the carbon monoxide oxidizes to carbon dioxide. The limestone acts as a flux to remove other impurities and help the iron physically separate from the rest of the burden. It comes out carrying a lot of the other impurities as slag.

Dolomite is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. Limestone that contains some dolomite is known as dolomitic limestone. Limestone that contains some dolomite is known as dolomitic limestone.

At the Iron Prince mine however, where the Katunga Dolomite has been exposed beneath the Lower Middleback Jaspilite, the principal impurity is iron which may comprise up to 30% of the rock. OneSteel finds this a convenient local source of flux for pelleted iron ore .

Limestone is composed of calcium carbonate and dolomite is composed of calcium magnesium carbonate so it is thought to be originated by the post depositional alteration of limestone via magnesium rich ground water. Dolomite consist all the properties of limestone, have same hardness, reacts with hydrochloric acid and bears the same colour (white to grey or white to light brown).

Dolomite is one of the compositions of limestone that can also be referred to as the sedimentary rock, both Limestone and Dolomite behaves in similar ways when subjected to heat and pressure. It is a carbonated mineral that is gotten from dolomite rock and is anhydrous in nature comprisinh mainly of calcium magnesium carbonate CaMg(CO3) 2 .
