  • Beneficiation of titaniferous ore with sulfuric acid
    Patent number: 7008602
    Abstract: Processes for the efficient and economical beneficiation of titaniferous ore are provided. A unique process for beneficiating ore comprising pretreatment of the ore by oxidation and reduction, followed by acid leaching with sulfuric acid has been developed. The acid used in this process may be recycled, which will thereby increase the efficiency of the process. Preferably the ore treated according to the present invention is ilmenite ore.
    Type: Grant

    Inventors: Earl Smith, Michael Robinson, Kirit Talati
  • Processes for treating iron-containing waste streams
    Patent number: 6800260
    Abstract: Processes for treating iron containing waste streams are provided. According to these processes, metal-containing compounds, particularly iron oxides are produced. These methods may, for example, be used in the processing of the waste streams from the chlorination of titanium-bearing raw materials and involve the use of certain combinations of neutralization and precipitation steps.

  • Production of carbon from coal granules prepared in a fluid energy mill
    Patent number: 4102812
    Abstract: Granular active carbon having satisfactory adsorbency and hardness characteristics and having a high proportion of its porosity in the below 2000 A range is produced from granules prepared from coal fluid energy milled until not more than 1% of the particles have diameters above 38 microns. The coal has a low ash and high carbon content and may have a British Standard Swelling number from 2 to 7 although it is preferred for the volatile matter content of the coal to be not more than 40% on a dry ash free basis. The granules may be produced by compacting milled particles having a temperature of from 50.degree. C to 250.degree. C between unheated pressure rolls.
