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 …
Achieving optimal wastes management and site remediation is one of the main challenges facing the mining industry around the world. This paper describes how …
Iron ore sintering is the main SO2 emission process in iron and steel industry. The flue gas of iron ore sintering has been cleaned by desulfurization equipment, which causes high capital and ...
Predictability of sulphur removal efficiency of iron ore (designated for production of orthopedic devices) has carried out based treatment temperature and mass-input of KClO 3 used as oxidizing agent. Results generated from experiment, derived model and regression model show that sulphur removal efficiencies increases with increase in both treatment …
Main reactions of iron ore pellets desulphurization are considered in details in a number of papers, in which the results obtained refer only to their isothermal heating. Therefore studies of ...
Abstract: Model for predictive analysis of the concentration of sulphur removed by molecular-oxygen-induced desulphurization of iron oxide ore (powdered potassium chlorate being the oxidant) has been derived. The model; %S = 0.0415/Logγ was found to

The main source of sulphur in the BF-BOF steelmaking process comes from coke. Even though roughly 40% of the sulphur in coal is removed in the coking process, typical sulphur levels in coke remain …
The achievement of higher sulfur removal rates has been an important goal since the development of sulfur removal techniques. In this research, an effort is made to separately introduce the various processes, industrial practices, and fundamental research activities to remove sulfur from iron ores, concentrates, or roasted iron ores.
Desulphurization using basic slag can be brought about by two mechanism: 1. Reaction takes place between basic synthetic or refining slag (which is added to the empty ladle) and the liquid steel being tapped. ... Brazil and Australia accounts for the major production of iron ore worldwide. As of 2020, Brazil had reserves of 34 billion metric ...
The results indicated that when high-phosphorus iron ore concentrates containing 54.92 mass pct iron and 0.76 mass pct phosphorus were directly processed through acid leaching, iron ore ...
