Modelling and simulation of a dense medium
Dense Medium Separation (DMS) technologies are used for light (coal, lithium) or heavy (chromite, iron ore, diamonds) minerals concentration, but also for ore preconcentration (Pb/Zn) or waste (plastics) Dense media are mainly formed from a suspension of magnetite or ferrosilicon in waterThe Dense Medium (Liquids) Heavy liquids are widely use in laboratory for appraisal of gravityseparation techniques on ores Heavy liquid testing performed to determine, Feasibility of dense medium separation on a particular ore Economic separating density, or to assess the efficiency of an existing dense medium (PDF) Dense Medium Separation (DMS) Chulodha Ferrosilicon is used in the dense medium separation of iron ore at Kumba resources, Sishen, South Africa Due to high cost and losses that occur during use, maximum recovery by means of magnetic separation is aimed for The purpose of this project was to determine the characteristics of the unused FeSi and then to characterise the changes that Characterisation of Ferrosilicon Dense Medium
