Effect of Teetering Pulp Density in Floatex Density Separator - A Case Study

The combination of gravity separators like air/wind/wet tables and spirals were used in multistages for the separation of heavier minerals such as monazite, zircon etc. from other minerals such as sillimanite, quartz etc. The introduction of modified commercially available hind-ered settling separators, like floated density/cross flow separators have revolutionized the separation techniques and simplified the earlier complicated process flow sheet. This paper deals with the use of such equipments and some experimental results on separation of fine sillimanite and quartz from the zircon rich fraction which was difficult to separate using conventional gravity concentrators.
