Blast furnace Produces pig iron from iron ore and sinter. The iron oxide of ore and sinter is reduced to iron with the help of carbon monoxide(Co) which is produced inside the furnace by the action of hot air at about 1000. oC with coke. Another purpose of coke is to supply heat for reaction and melting iron .
Modeling Sintering Process of Iron Ore 27 Fig. 3. Multiple phases considered in the present model. In this model it is assumed that the liquid phase formed will move together with the remaining solid phase due to the viscosity, thus, equations for momentum transfer and
Cutting Edge Technology for Iron Ore Mineralogical Analysis Business Challenge. SOLUTION FOCUSED TECHNOLOGY QEMSCAN is a key technology for the analysis of iron ore. QEMSCAN provides quantifiable data for studies into the various iron oxide species including grain size distribution, liberation, gangue association and predictive recoveries.
Why is Iron Ore Valuable? Iron ore is a rock from which the metal iron is extracted. About 98% of the world's iron is used to produce steel.. Pure iron is an element and a soft grayishwhite metal. Other than meteorites that fall from the sky, iron is never found by itself in nature.
SGS announces that it has officially incorporated the TESCAN Integrated Mineral Analyser (TIMAX) into its suite of automated mineralogy offerings across this move, SGS says it is able to offer its clients better detection limits, superior imaging and faster turnaround time and results.

Many different approaches have been used in the past to characterise iron ore sinter mineralogy to predict sinter quality and elucidate the impacts of iron ore characteristics and process variables on the mechanisms of sintering. This paper compares the mineralogy of three sinter samples with basicities between
quality iron ore resources are being depleted due to the heavy demand, and thus it is necessary to continue improving sintering technology in order to use lower quality iron ores in the raw mix. The blast furnace demands sinter with high strength, a low RDI, high RI, low fines content, good average calibrated sinter .

Fr ohlichov a ... thermodynamic study was to evaluate the possibilities of charcoal utilization in ironore sintering process. Thermodynamic analysis has shown that the main factors determining ... coal. The sinter batch was charged as micropellets into ...
Iron ore sinter remains an important feed for the production of iron and steel, and research continues into the improvement of sinter quality for economic and environmental reasons [1,2]. In the authors' previous paper , the mineralogy of an industrial sinter sample was analysed
Iron ore with high hydroxyl content such as goethit is widely spread in Indonesia. Such iron ore is not used as feed in ironmaking industry. However due to limitation of primary iron ore reserve such material is an option to substitute the conventional iron ore. Unfortunately the characteristic of iron ore with high hydroxyl content is totally different to conventional iron ore.

In iron ore, iron is presents in its oxidised form. In iron reduction processes, a reducing agent, based on carbon or hydrogen, removes the oxygen from the ... and the latter is often processed into sinter or pellets. Both natural gas and coal are used as reducing agents. The blast furnace requires ... values used in the analysis in chapter 4 ...
furnace. Furthermore, using coke breeze without sieving in sintering of an iron ore decreases the vertical velocity of sinter machine and increases the reduction time. Keywords: Coke fine, Granulation, Iron ore, Sintering process. 1. Introduction The price of energy is dramatically increasing by the day. In this respect, coal and
The quantitative evaluation of minerals by scanning electron microscopy (QEMSCAN) analysis (FEI, Hillsboro, OR, USA) of roasted stone coal showed that there were small amounts of apatite existed in this roasted stone coal and the apatite was the only source of P.
Thermodynamic analysis and reaction behaviors of alkali metal elements during iron ore sintering ... chloride content and coal ratio of raw materials indicated that increasing basicity level, rising coal ratio and adding CaCl 2 promoted the removal of alkali metal elements into the flue gas. However, with sulfur content increasing in raw ...
The main effect on iron ore mineralization performance in the sintering process is the grain size of raw material and chemical composition. The results show that particles can mineralize, but + particles remain a nucleus in sinter. This paper analyses the effect of the chemical composition on mineralization characteristics of liquid production.
