Biomass for iron ore sintering
WebMay 20, 2024 · Special Issue Information. Dear Colleagues, Iron ore sintering is an important stage in the production of steel from iron ore. Sinter can constitute more than 60% of ferrous burden in modern blast furnaces in Japan and most blast furnaces in Europe. Iron ore sintering is a high temperature process which converts iron ore fines (<6–8 … WebSep 3, 2016 · Many kinds of biomass can be used in the iron ore sintering process, but two issues should be considered. The first is the processing cost, and the second is the VM level. For example, palm trees are popular in South East Asian countries ; after the palm oil is extracted the shells are dumped as garbage or used as crude fuel in rural areas.
