Iron ore pellets are fed directly into the blast-furnace. Iron ore fines are mixed at the ironworks with limestone and other minerals and pre-fired at low temperatures to form a sinter, i.e. agglomerates that can then be fed to the blast-furnace. Finely divided quicklime is often added to the sinter mixture to assist in binding the material to improve productivity and give a stronger sinter
Get PriceLimestone. 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.

Get PriceEarlier investigators 4,5,6,7,8,9,10,11) have studied on the use of hydroxide lime in iron ore pellets and found some encouraging results. De Sauja 4) has shown the advantages of using hydrated lime in pelletzation and reported to achieve average 367 kg cold crushing strength (CCS), 18.5% swelling index and 69% reducibility index of indurated pellets. Very high green compressive strength (4 kg
Get PriceRecommendations based on soil depths of 200mm/8in (arable) and 150mm /6in (grassland). Greater depths of soil will require more lime. Maximum surface application for grass is 7 tonne/ha (3 tonne/acre). Minimum application rate: 2 tonne/ha (1 tonne/acre).

Get Price07/07/2017· The first process takes place at limestone mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw limestone is further processed. Example is sinter plant where the raw limestone is crushed in hammer mills to – 3 mm size (generally in the range of 85 % to 90 %). Calcination
Get PriceLoss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.This may be done in air, or in some other reactive or inert atmosphere.
