    determination of iron in the hematite ore. In designing this experiment to determine the iron in the oxide ore, the role that the hydrochloric acid plays in the reaction was looked upon with curiosity. In light of research and chemical intuition, it was found that the role of excess hydrochloric acid is disputed by some chemists.

  • Geostatistical methods for estimating iron, silica and

    Many iron ore deposits have a weathered zone (Hardcap) near the surface which is highly variable in grades. Estimating the amount of ore grade material (HG) in this zone is difficult as a result of this variability. The Section Seven Deposit at Tom Price is largely mined out and has production data
