  • Process and equipment for the production of direct reduced iron and/or pig iron from iron ores having a high-phosphorus content
    Patent number: 8673208
    Abstract: A process and apparatus for refining iron from high-phosphorus content iron ores. The process involves mixing a high-phosphorus iron oxide ore and an alkaline solution of pH between about 12.5 and 13.5, screening the mixture by gravity to separate an alkaline-high-phosphorus solution from a low-phosphorus iron ore; and treating the low-phosphorus iron ore with lime and a natural gas.
    Type: Grant
    Filed: September 7, 2012
    Date of Patent: March 18, 2014
    Assignee: C.V.G. Ferrominera Orinoco C.A.
    Inventor: Henry Rafael Bueno Colina
