Dolostone (Limestone)

Limestone readily reacts with hydrochloric acid and produces carbon dioxide (CO2) as a gas. By contrast, dolostone is less reactive and normally must be in powdered form to react visibly. Pure dolomite contains 54.28 percent calcium carbonate and 45.72 percent magnesium carbonate. Dolostone is commonly referred to by its mineral name, dolomite.

 · Dolomite is a limestone compound containing calcium and magnesium. The best mixtures contain 8 to 12 percent magnesium and 18 to 23 percent calcium. These elements influence the soil pH while providing valuable nutrients to your plants. It''s helpful to know Dolomite can often contain sodium, but it should only be 2 percent or less.

Limestone Mining

Lime is a mineral made by heating limestone or dolomite in a kiln. Lime is used in a variety of chemical industries, in sugar processing plants, in steel mills, sewage treatment plants, and at paper mills. "Burned" or kilned limestone was also used as plaster and mortar in the homes of early settlers, and even into the mid-20th century.

Why is limestone used in blast furnace? – Mvorganizing

 · In iron and steel Industry, limestone and dolomite are used both in ironmaking and steelmaking. Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Further lime from limestone reacts with the S present in the raw materials to form calcium sulphide (CaS) which goes into slag.
