  • Enhancing Magnetite Concentrate Granulation By Blending

    Unlike hematite ore, magnetite concentrates do not granulate easily at low binder dosage to yield coarser granules due to the absence of nucleus particles. This motivates the present study to harness the complementary properties of hematite ore to enhance granulationUnlike hematite ore, magnetite concentrates do not granulate easily at low binder dosage to yield coarser granules due to the absence of nucleus particles. This motivates the present study to harness the complementary properties of hematite ore to enhance granulationMany sinter plants in China use magnetite concentrate and imported sintering fines in their blends. It has been found that sintering performance is improved with the addition of the sintering fines.
