The use of Ferrosilicon in diamond recovery

There are a few methods when it comes to mineral / diamond recovery and separation techniques, of which the most commonly used is the process of Dense Medium separation, also known as the sink-float method.

The process of Dense Media Separation requires the use of Ferrosilicon powders, which is mixed with water to form a fine suspension until it reaches the desired density (close to the density of diamonds). The diamond or mineral bearing material is the submerged into the pulp mixture, in order for dense media separation to take place. Particles that are denser than the medium will report to the process underflow as sinks, while less dense particles will report to the process overflow as floats. Dense Media Separation is widely used in diamond recovery, due to the effectiveness of the process, and because it is cost-effective.
