Blast Furnance Chemical grade limestone is important to the process as it is the primary raw material which helps remove impurities from the iron ore and produces a slag with low melting point and a high fluidity. Consistency of the chemical grade limestone for chemistry and sizing is critical for efficient blast furnace operations and cost control.

- Background Information Limestone is a chemical sedimentary rock that is created from the remains of calcium bearing organisms and chemical precipitants. The calcium can come from the shells and/or the skeletal fragments of deceased organisms.

Limestone Limestone has many industrial uses. It is used as a building material, as a raw material in the manufacture of portland cement, quicklime, etc. Calcium is an important micronutrient. Several commercial drugs (antacids and calcium supplements) are nothing but pulverized limestone (calcite) .imestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are named dolomite rock. Carbonate rocks together make up one-fifth of all sedimentary rocks in the stratigraphic record.

Uses for Limestone Powder Steel. Limestone is used in making steel products. Limestone is added to mix with impurities in the melted iron, producing slag. The slag is separated from the iron leaving it clean of all impurities and limestone, which is then made into steel.eutralizer. Limestone can be added to water to remove impurities and pollutants. Since limestone is primarily made of calcium carbonate, a base substance, it can be used to neutralize acidity in industrial waste and run-off. Limestone can also be used to reduce soil acidity for agriculture.

- Depending on the quality of the deposit, limestone can be quarried to service the needs of the building and construction industries. For example, certain types of limestone such as that found in North Otago can be cut into blocks suitable for direct use as building stone (Oamaru stone).In road construction, limestone aggregate direct from the quarry can be used as base material.Lower-grade limestones, particularly ones with some clay content, can be used in the production of cement for use in the building and construction industry.Cement is a key ingredient of concrete, huge volumes of which are poured each day to serve as roading, foundations, structural beams and columns.or example, certain types of limestone such as that found in North Otago can be cut into blocks suitable for direct use as building stone (Oamaru stone).

Metallurgy â Modern Methods of Iron Ore Smelting Limestone is used as a flux to separate the gangue from the molten iron ore, the accumulated slag and the molten iron being tapped from two tap-holes at the bottom of the furnace.

unit 6 - rocks and minerals What is Limestone? Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris.

Limestone: A Crucial and Versatile Industrial Mineral Commodity Limestone has many industrial uses and can be used as mined or processed into a wide variety of products. It is the raw material for a large variety of construction, agricultural, environmental, and industrial materials. Limestone is used in construction almost everywhere. In 2007, crushed limestone was 68% of all crushed rock produced in the United States. Also, limestone is the key ingredient in making Portland cement.

Limestone Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock.imestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock.

Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts.

- Uses of limestone. Limestone, quicklime and slaked lime are all used to neutralise excess acidity-which may be caused by acid rain-in lakes and in soils. Limestone is used as a building material, and to purify iron in blast furnaces.It's also used in the manufacture of glass, and of cement (one of the components of concrete).he main uses of limestone and its products. 1  Limestone (CaCO 3) can be used as a building material and in the manufacturing of iron. 2  Glass-heated with sand and soda (sodium carbonate). 3  Cement-heated with clay in a kiln. 4  Concrete-mixed with sand, water and crushed rock. 5  Mortar-mixed with sand and water. 6  Quicklime-heated.

- What is Limestone. Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago.

Why Is Limestone Good to Use As Building Material? Limestone represents roughly 10 percent of all sedimentary rock in the world. Limestone generally forms on the shallow floors of tropical waters when seashells, sand and other sediment are compressed together. Limestone can be called a young marble. Crystals of cement grow around the young marble from grains that are made from animal seashells. A famous architectural marvel created with limestone is the Great Pyramid of Giza.

What Is the Purpose of Crushed Limestone? Limestone for the garden should be very finely ground. Limestone is a common sedimentary rock found all over the world. The primary constituent of limestone is calcite, and the primary mineral in calcite is calcium. A closely related rock known as dolostone contains both calcium and magnesium. Crushed limestone is used for various purposes, but in the garden it is primarily a soil amendment applied to correct soil acidity and provide important nutrients.

Limestone Limestone is a sedimentary rock in the class known as chemical sedimentary rocks. It is composed chiefly of calcite, CaCO 3, and constitutes about 10 percent of all sedimentary rocks.Limestone may form inorganically or by biochemical processes.oral reefs are examples of limestone produced in the form of the skeletons of the coral invertebrate animals. Calcium-carbonate secreting algae live with the corals and help to cement the structures together.
