B.Sc. (Visitor) SYNOPSIS The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required.

Read MoreDense Medium Separation (also called Heavy Media Separation) is a well-established density separation process. Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetric-based separation. Due to the robustness of the process, DMS can be used in the separation of minerals, ore bodies and ...
