  12. Investigating collector and depressant performance in the flotation of selected iron ores by Mhonde, Ngoni Pepukai

    Published 2017
    “…As the excessive extraction of high grade iron ore reserves has led to the rapid depletion of these ore bodies, there is a growing need to extract and upgrade low grade iron ores into more economically viable products with an iron content in excess of 50%. …”

  13. Assessing the Influence of mineralogy and texture on the ore breakage characteristics of drill core and crushed ore using the JKRBT by Hill, Herbert Hill

    Published 2021
    “…Increased textural variability is the largest contributor to mineral processing challenges in terms of mill throughput and flotation concentrate grades. Processing of ores with high textural variability often results in reduced throughput and the recovery of lower grade product, if low-grade material is not eliminated prior to arriving at the concentrator. …”
