    Iron Ore Microfines Sintering

    Iron ore microfines and concentrate have very limited uses in sintering processes They are used in pelletization however this process is cost intensive Further the microfines of non coking coal and other carbon bearing materials e g blast furnace flue dust(BFD) and coke fines are not used extensively in the metallurgical industry because of operational difficulties and handling.Steelmakers are increasingly motivated to use iron ore resources with a wider range of grades and mineral types that were previously considered unsuitable or uneconomical for sintering In this respect specific issues which now require further investigation and understanding include the sintering of ore types with overall higher gangue content elements that cause problems in the steel.Micropellets in sintering of iron ores Improved sinter mix preparation while using challenging Publication metadata The objectives of this project is to improve sinter bed permeability and sinter quality by a better control of all preparation phases and a better understanding of their impact on the sintering process in order to allow an optimal use of challenging ores (finer and or poorer.Ultrafine iron oxide wastes such as slime blue dust and Linz–Donawitz (LD) converter sludge have very limited use in sintering of iron ore due to their excessive fineness (−50μmm) Pelletisation of these ultrafine materials for use in blast furnace involves high temperature curing which is a highly energy intensive process.
