  • The use of lowtoxic heavy suspensions in mineral sands SAIMM

    Background. Heavy liquids have wide use in the laboratory for the appraisal of gravityseparation techniques on ores.

  • Density Separation

    Heavy liquids separations are generally done in separatory funnels. The procedure is very simple. The sample is placed in the separatory funnel and the heavy liquid is added. The funnel is then left for some time to permit light minerals to float and heavy minerals to sink. When the minerals have been separated, the
