  • Iron Sponge Process an overview ScienceDirect Topics

    The iron oxide process (also known as the iron sponge process) is the oldest and still the most widely used batch process for sweetening natural gas and NGLs (Duckworth and Geddes, 1965 Anerousis and Whitman, 1984 and Zapffe, 1963). The process was implemented during the 19th century.

  • Pig Iron Manufacturing Process

    Pig Iron Impurities. Increased basicity of the slag causes more of the sulphur to be slagged. By thinning the slag a small amount of fluorspar assists in sulphur elimination from the pig steel, but an excess has the contrary effect. Continuous operation of the furnace does not

  • Blast Furnace operation: HOW A BLAST FURNACE WORKS

    Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3 ) or Magnetite (Fe 3 O 4 ) and the iron content ranges from 50% to 70%.

  • [GIFS] The 5 Stages of the Mining Life Cycle Operations

    The fifth and final stage in mining operations is closure and reclamation. Once a mining site has been exhausted of reserves, the process of closing the site occurs, dismantling all facilities on the property. The reclamation stage is then implemented, returning the land to its original state.

    Fig 1 DRI process principle. Major DRI production processes are either gas based or based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor, the reduction reaction takes place is a shaft furnace.

  • Iron Ore and Pellets

    Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cuttingedge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and household appliances.

  • Iron ore Wikipedia

    Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygeniron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen.

    Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steelmaking process. Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.
