    Understanding Sinter and Sinter Plant Operations

    Understanding Sinter and Sinter Plant Operations Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pre-treatment step in the production of iron, where fine particles of iron ores and also secondary iron oxide wastes (collected

    Minerals Special Issue : Mineralogy of Iron Ore Sinters

    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 mm in size, too small for direct feed into the blast furnace) into larger agglomerates containing bonding phases, unmelted nuclei and pores. The sinter must possess the chemical

    Theory and Practice of Sintering of Iron ore IspatGuru

    The softening and melting behaviour of three lump hematite ores and a sinter has been determined in an outfit which operates under load. It has been found that the beds of lump ores contract much earlier than sinter by the formation of fayalite, with a low melting temperature component to be around 1175 deg C to 1205 deg C. No fayalite forms in sinter and at higher temperature melts which are generated appear
