• Improving efficiency of gravity separation of fine iron ore materials

    The paper presents the results of the research aimed at improvement of efficiency of gravity separation of fine fractions of iron ore materials produced at the mineral processing plant of Olkon JSC. Using computer modelling it was shown that spiral separators provide more effective processing of fine fractions of tailings of primary magnetic separation compared to jigging.

  • Gravity separation

    Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

    The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately /m3). Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities. Gravity separators include jig
