iron ore fines agglomeration

Sinter plant - WikipediaSinter 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.Agglomeration behaviour of steel plants solid waste and its effect on .The amount of coke breeze and iron ore was fixed to 300 g and 3 kg respectively, whereas the other raw material mixes are calculated for aforesaid basicity of sinter. The sinters produced in experiments have been graded as S1, S2, S3, …, S15 by varying line fines, i.e. flux and the amount of waste made pellets which.

iron ore fines agglomeration,A review of binders in iron ore pelletization - Taylor & Francis Online

The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated, and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces. The most common agglomeration technique is pelletization, which requires.
