  • Iron Ore Reduction - an overview | ScienceDirect Topics

    Hydrogen can serve as a reducing agent and the most prominent application appears to to be iron ore reduction. A variety of direct reduction of iron ores without coke has been carefully studied for a long time. These use hydrogen, carbon-monoxide and carbon in a combination. The reason for the development is due to the following:

  • Effects of Multi-stage Grinding Process and Grinding,

    01/01/2015· Beneficiation tests Two kinds of experimental schemes for the desulfurization of high-sulfurous iron ore were proposed to find industrially viable route to produce high-quality iron concentrate. The first scheme is the separation process of one- stage grinding. The samples were firstly ground in a lab-scale conical mill with the type of XMQ-240×90. The next step was a one-stage magnetic

  • How to Make Steel from Iron Ore and Its Future Prospect,

    After the raw materials are solved, they will be put into the blast furnace, and these raw materials will be reduced into molten iron containing carbon in the blast furnace. The main purpose of a blast furnace is to remove a large amount of sulfur from iron ore resources. In addition, coking and sintering can remove some harmful impurities from iron and steel. The molten iron obtained will be transferred to the

  • From pig iron to crude steel - tec-science

    During this so-called manganese desulfurization, the iron sulfide (FeS) forms manganese sulfide (MnS) in the pig iron melt: FeS + Mn ⇌ Fe + MnS (exothermic) The manganese sulphide, which is insoluble in liquid pig iron, is deposited as slag on the melt.
