what is the role of limestone in extraction of iron??

5 Answers. The main role of limestone in extraction of iron is to decomposes in hot furnace and form the calcium oxide. Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide.

Limestone

Limestone. Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).

Lime in the Steel Industry

Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces. Lime removes impurities (silica, phosphorus, sulfur) from the steel being manufactured. The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel.

How does limestone change throughout the rock cycle? | Socratic

Limestone usually starts in the biosphere, gets recycled into the lithosphere or geosphere, moves to the atmosphere then back to the biosphere. Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions

The acid test is used to determine the amount of calcium carbonate and type of lime present in the limestone. The procedure of acid test is as follows. A teaspoon of powdered lime is taken in the test tube and 10 ml of dilute hydrochloric acid is added to it. Substances are stirred thoroughly and kept the mix in a safe place for 24 hours.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

The type of limestone treatment system used depends on the amount and ionic state of the iron in the AMD. Three groups of AMD are considered here (1) low iron AMD, (2) ferric iron AMD, and (3) ferrous iron AMD. Low Iron AMD. Low iron AMD is the easiest to treat. Limestone beds (Figure 8) and pulverized limestone (Figure 9) can be effectively used.
