  • CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

    consists of a cellular mass of ore bonded in a slag matrix. The sinter mix, besides the ore fines, usually contains other materials like flue dust, return fines, limestone and/or dolomite etc., in order to control the properties of the product as well as to utilize industrial waste. Return sinter fines having lower fusion temperature than the raw mix serve as seeds for initiation of the sintering process.

    The Sintering Process of Iron Ore Fines IspatGuru

    09-03-2013· The process of sintering is basically a pre-treatment process step during iron making for the production of the charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes (collected dusts, sludge and mill scale etc.). The sintering technology was originally developed for the purpose of utilizing in the blast furnace the iron ore fines and the iron present in the metallurgical waste of a steel plant

    Sinter plant Wikipedia

    Sinter 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 make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

    Iron ore (fines) Cargo Handbook the world's largest

    Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).
