While diamond recovery methods have become more sophisticated over the years - to continually improve recovery, operating efficiencies and maximise value - they still follow the golden rules of mineral dressing, "viz. careful liberation" of the mineral in a staged manner if necessary, followed by "extraction and concentration thereof'.

In a Dense Media Separation (DMS) 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.

Figure 11.1: Principle of dense medium separation. Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the …

10. Diamond is the hardest-known mineral. However, the hardness of diamond is directional. It is hardest parallel to its octahedral planes and softest parallel to its cubic planes.
