Direct Reduced Ecology

  • Direct Reduced Iron - Open Source Ecology

    Direct-reduced iron (DRI) is a metallic material formed by the reduction (removal of oxygen) of iron oxide (iron ore) at temperatures below the melting point of iron. DRI is produced by the use of a reducing gas (mostly a mixture of hydrogen and carbon monoxide). The temperatures for this process are significantly lower than those in a blast furnace, and capital requirements are also lower.
