Apr 01, 2016 The iron ore sintering process is the main source of SO 2 emissions in the iron and steel industry. In our previous research, we proposed a novel technology for reducing SO 2 emissions in the flue gas in the iron ore sintering process by adding urea at a given distance from the sintering grate bar. In this paper, a pilot-scale experiment was carried out in a commercial sintering plant.

high-grade, low sulfur iron ore. However, with the depletion of high-grade resources, the requirement of low cost production and the expansion of production capacity, the load of SO2 also rises subsequently. So the new FGD project would have to be built. In 1970s, the research of sintering flue gas desulphurization was begun in the world.
Nov 04, 2018 Most of the desulphurization occurs as the HM droplets pass through the liquid slag layer. Hence the thicker the slag layer the more effective is the desulphurization. Trace metals. Non-ferrous metals also originate in coke, coal, and ore burden. Coals with P content below 0.08 are normally desired.

The idea of rolling moist fine ore in a drum to form balls and then drying and firing it was first patented by A. G. Andersson in Sweden in 1912. Further development was performed to bring the idea to reality.
An iron ore sintering plant may have several combinations of control equipment described above as APCD. According to Xu et al. 2017, a typical configuration is the use of ESP, FF and FGD. These authors evaluated the efficiency of mercury removal in three sintering plants with the following APCD configurations 1

In the hot metal desulphurization process, efficiency and metallic yield both partly depend on the quality and reliability of desulphurizations fluxes and flowability. Carmeuse provides fluidised milled lime in its purest and finest form to the specifications or blended with slag liquefiers and magnesium metal.
Nov 30, 2017 In addition, the ore cannot be beneficiated easily like Itakpe and Oshokoshoko iron ores because of its texture. This work studied the beneficiation, dephosphorization and desulphurization of Agbaja iron ore. The raw ore was beneficiated using several techniques namely oil agglomeration technique, rapid magnetic separation technique, Humphrey ...
Feb 01, 2018 Desulphurization of iron ore concentrates may be achieved by using both physical and chemical methods. Physical processes are cost-effective methods but are not effective in separating the finely dispersed sulphide minerals and those bound to the mineral structure. The common iron ore desulphurization method is flotation.

Abstract. Iron ore sintering is an important part during the ironmaking process, and a large amount of SO 2 is also generated. Our previous research shows that it is an effective way to reduce SO 2 content of flue gas by adding urea to a special sintering material zone position. In this paper, the mechanism of selective desulphurization by adding urea during the iron ore sintering was carried out.
