  • Iron-ore concentrates in iron-powder production

    Iron powder may be produced from natural iron ore. The production of iron-ore superconcentrates containing less than 0.3% silica for iron-powder manufacture is considered. The adjustment of magnetite concentrates from Olenegorsk and Lebedinsk enrichment plants and the enrichment of magnetite ore from the Kursk Magnetic Anomaly is investigated.

  • Production of an iron ore concentrate from the iron-rich

    Removal of gangue materials, principally silica and alumina, from a magnetically-separated, iron-rich fraction of bituminous coal fly ash shows promise of yielding an iron ore grade concentrate. As separated, the iron-rich fraction contains 65 to 75 wt. % iron oxides or about 50 % of the iron originally in the ash.

  • Production of High Grade Iron Ore Concentrates Using Flota

    flotation cells. CPT Inc. has developed a flotation process for the production of Direct Reduction (DR) as well as Blast Furnace (BF) grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.

    divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder. The iron ore used at Höganäs is a magnetite slick (powdery Fe 3 O 4) obtained by selective mining from mines in the north of Sweden and Norway. This magnetite slick, which by nature contains only

  • Iron processing Britannica

    By the middle of the 16th century, blast furnaces were being operated more or less continuously in southeastern England. Increased iron production led to a scarcity of wood for charcoal and to its subsequent replacement by coal in the form of coke—a discovery that is usually credited to Abraham Darby in 1709. Because the higher strength of coke enabled it to support a bigger charge, much larger furnaces became possible, and weekly outputs of 5 to 10 tons of pig iron

    Ore containing less than this is first crushed and ground into a powder and concentrated by flotation. It is then rolled into balls and heated in a furnace to produce pellets the size of marbles. This process takes place near the mine, reducing the long-distance transport of waste material (clays and other silicates).
