Calcium-based desulfurization ash (CDA) is mainly produced in dry and semi-dry flue gas desulfurization processes. The property of CDA is extremely unstable because its main component, calcium sulfite, makes it difficult to be directly applied to the field of building materials. The modification of desulfurization ash can be realized by high-temperature oxidation and wet …

Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
The SBM desulfurization with limestone crusher is a comprehensive domestic and foreign high-efficiency pre-mill technology, the main technical parameters optimized design developed from …
Iron Ore. Iron usually exists in compound, especially in iron oxide. Several kinds of valuable iron ores are magnetite, hematite, limonite and siderite respectively. The grade of iron ore refers to the mass fraction of iron element in iron ore, say, the iron content. For example, if the grade of iron ore is 62, the mass fraction of iron element ...
Results from the industrial pilot plant and the full scale plant at the iron ore sinter plant of voestalpine, Linz, A which both have been built by Siemens VAI are reported.
Iron ore sintering is an important part of a long steelmaking process with sulfur dioxide emissions accounting for 40%–80% of the total sulfur dioxide emissions in steel companies [1,2,3,4].Semi-dry flue gas desulfurization technology combines the characteristics of wet and dry flue gas desulfurization processes, and it has significant advantages such as low …
For dry off-gas desulfurization by chemisorption in iron ore sinter plants hydrated lime is usually used as reactant. In some other off-gas cleaning applications with a gas temperature above 140°C sodium bicarbonate is used instead of hydrated lime. An advantage of sodium bicarbonate is the higher desulfurization efficiency. Additionally, cooling of the off-gas to a temperature …
The proper feed for the pelletizing plant must have iron and the Blaine number more than 67 % and 1900 cm 2 g-1 and sulfur content less than 0.1 %, respectively.
Configuration of the HM Desulfurization Plant at Isdemir. ... The deoxidation and the desulfurization limits of liquid iron by calcium are calculated to be 1.6 mass ppm O (at 15 mass ppm Ca) and 3 ...
The iron ore sintering process is the main source of SO2 emissions in the iron and steel industry. In our previous research, we proposed a novel technology for reducing SO2 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 …

There are four stages where sulphur can be removed: in the blast furnace (BF), during hot metal (HM) pretreatment, in the converter and during the secondary metallurgy …
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.
There are various types of iron ore in China, among which high-sulfur iron ore resources are abundant and widely distributed. This type of ore is mainly composed of hematite (Fe 2 O 3), magnetite (Fe 3 O 4), pyrite (FeS 2), quartz and other non-metallic minerals, in which the sulfur element mainly exists in the form of pyrite and sulfate.Pyrite is a naturally occurring …
