Feb 16, 2017· Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
Fraction of 2 mm to 5 mm should be as higher as possible for better sintering process. Normally we get iron ore fines that is having 100 mesh (- 0.15 mm micro fines) minimum of 25 % and 15 % to 20 % +8 mm size. We are planning to install on-line screening to separate + 8 mm size from the lot and the

Feb 12, 2021· Lower grade ores such as goethite have become increasingly used in iron ore sintering worldwide.[1,2] From a mineralogical perspective, the texture of goethitic ores is typically composed of spheroidal grains and porous, with varying amounts of coarser, goethitic fossil wood in a goethite matrix.[1,3,4] From a geometallurgical perspective, goethitic ores are classified into brown, ochreous ...
Ore Coke Flux. Sintering is significantly cheaper & has significantly lower barriers to entry. Sintering is the intermediate step in producing either-laterite nickel feed for an EAF/Blast Furnace [Ni PI], or. iron ore feed for the steel industry. Capital Costs for a sinter plant are low-Approx. US$4M per 100,000 tpy production module
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
Iron Ore Sintering Process in Steel Manufacturing ‹ Cement, Coal ... The basicity of sinter feed material is an important parameter in the efficient operation of the sintering and iron making process. Basicity is a calculated chemical parameter composed of the ratio of two or more elements that are known to affect the alkalinity of the material.

Sintering of Iron Ores in a Millipot in Comparison with Tablet Testing and Industrial Process . Abstract . To explore the feasibility of small-scale sintering pot testing, a 'millipot' facility (diameter of 53 mm and height of 400 mm) was established and used to examine the sintering performance of iron ores and other non-traditional ferrous ...
Feb 04, 2021· In the iron ore sintering process, the heat is supplied majorly by solid fuel. Higher is the solid fuel, more is the formation of Fe 3 O 4 and FeO [2, 3]. The degree of reduction is indicated by the amount of Fe 3 O 4 and FeO. Increase in FeO increases the strength of the sinter. The other mineralogical phase that enhances the strength of the ...
