Extraction of Iron. Chemistry of the blast furnace . Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace ... The main impurity is silica (sand or rock) which is silicon dioxide.
An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.

Calcium carbonate has the chemical formula CaCO3. In nature, marble, limestone and chalk contain calcium carbonate. By processing calcium carbonate from marble, one obtains precipitated calcium carbonate, which is ground into a powder called ground calcium carbonate. Ground calcium carbonate has many industrial, medicinal and pharmaceutical uses.

ions. The dissociated carbonate ion will combi ne with the calcium ion supplied to form the precipitate of calcium carbonate, CaCO3. The calcium carbonate may serve as bridges between the sand grains restricting their movement, hence improving strength and stiffness of the material, and subsequently reducing the liquefaction susceptibility.

Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide.
separating calcium carbonate from sand · Best Answer: calcium carbonate and silicon dioxide is not dissolving in water so first step you need to filter the solution than you get calcium carbonate and sand mixture and salty water to separate sand from CaCO3 you need Hydrochloric ac HCL will dissolve the CaCO3 from the mixture so you need to filter it again...
Calcium carbonate is sometimes prescribed as a supplement for those whose diet is lacking in calcium, the body's most abundant mineral and one of its most important. Other forms include calcium citrate and calcium lactate. Abnormally low levels of calcium can be detrimental to body function, as in the depletion of calcium reserves in the skeleton.
