  • 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.
