  • MIDREX® Process - Midrex Technologies, Inc.

    The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H ₂ and CO content. These gases react with

  • Iron Ore Smelting Process - Bright Hub Engineering

    The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being

  • Operating mode recognition of iron ore sintering process

    2020-03-01· Sintering is a thermal agglomeration process, and its main raw materials are iron ore, returning sinter ore, fluxes, and coke (Fernández-González, Ruiz-Bustinza, Mochón, González-Gasca, & Verdeja, 2017). The high energy consumption and serious pollution associated with the sintering process have always been an important concern of iron and steel companies. Operating mode refers

  • Direct reduced iron - Wikipedia

    Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

  • How is Iron Refined from Ore? (with pictures)

    2020-11-24· Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. In its natural form, iron ore has a
