  • Determining Iron Grades of Ores or Concentrates

    The iron grade of a high pyritecontaining ore was determined by the new method, and the results were compared to those obtained by the traditional roasting or HNO3 titration. The new method was found to provide iron grade values close to the roasting method. The proposed method was tested on a number of samples with known iron grades.
