In a Dense Media Separation (DMS)/ Heavy Media Separation ( HMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond-bearing material is added to begin the separation process of the heavier minerals from the lighter material.

Heavy Media Separation Process

Mar 19, 2017  The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle
