11.17 Lime Manufacturing
Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains 30 to 45 percent magnesium carbonate, it is referred to as dolomite, or dolomitic limestone. Lime can also be

[Solved] Function of limestone in the manufacturer of iron
The main function of limestone in the extraction of iron from haematite is as a flux. Limestone is used as a flux to remove the impurities and dirt from haematite. Limestone decomposes in a hot furnace and forms calcium oxide (CaO). Iron is extracted from its ore, haematite, in a blast furnace. The ore is put into the furnace along with

Lime Production: Industry Profile
Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.

Limestone is a rock made of calcite. Most limestone is grey, but all colours of limestone from white to black have been found. Scientists test natural rock to see if it is limestone by pouring cold diluted hydrochloric or sulphuric acid (10% solution or vinegar) on it. Limestone gives off bubbles of carbon dioxide.
