    The active catalyst for ammonia synthesis is originally derived from magnetite-based ore (Fe 3 O 4) incorporated with several promoters, such as calcium oxide, alumina, potassium oxide, etc. Today, the composition of the catalyst used in industry is still more or less identical to that demonstrated in 1910 ( Thomas & Thomas, 1997 ).

  • Iron ore Wikipedia

    Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and

  • Processes for Beneficiation of Iron Ores IspatGuru

    Mar 28, 2015· Washing is the simplest iron ore concentration process that takes advantage of the high specific gravity and comparatively coarse size of the iron bearing minerals to separate them from the finer, lighter, silous gangue which is predominantly quartz and clay minerals.

  • Concentration of Ore Definition, Types and Properties of Ore

    Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them.

  • Iron ore BHP

    What is iron ore Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
