ABSTRACT
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. The modelling results were confirmed with industrial spiral separation tests. A separation technology for processing the tailings of primary magnetic separation was developed.
