  • Iron Ore to Sintering to Steelmaking - Analyzing Metals

    But before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace. We recently wrote about sintering in our sister blog, Advancing Mining. Read the article to learn more about how sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials.[...]

    How is iron extracted from its ore? It’s a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulfur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.[...]

  • Roasting in Metallurgy - Mineral Processing & Metallurgy

    In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution.[...]

    Sep 18, 2019· The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure \(\PageIndex{2}\)) in which the roasted ore, coke, and limestone (impure CaCO 3 ) are introduced …[...]
