DMS Diamond Plant – DMS Powders Suppliers

Diamond plants make use of a specialised method called Dense Media Separation, for the separation of diamonds from other material when mined. This method works by separating valuable material (diamonds) from water-based materials, through by means of gravity. The dense media separation of diamonds process requires the use of ferrosilicon powders, which is produced by DMS Powder.

DMS Powders is a top manufacturer of ferrosilicon powders, used by many diamond plants in the processing of separating diamonds from other material. DMS Powders is world-class supplier of ferrosilicon powders for dense media separation, supplying clients with high quality products for this purpose.

Contact DMS Powders today for more information about our ferrosilicon powders and products for the Dense Media Separation of diamonds.

DMS Powders

The process of Dense Media Separation in Diamond plants

Dense Media Separation can be explained as a sink-float method and technology used within the coal, iron ore and diamond industries, which is used to separate valuable material from other material.

Powdered ferrosilicon as supplied by DMS Powders is used in this process. Ferrosilicon is an alloy of iron – this powder is suspended in water, forming a heavy liquid pulp, which comes close to the density of diamonds. The material bearing the diamonds is then added to the fluid, and the separation process will commence. Heavier minerals will sink, and lighter material will float and rise to the surface – efficiently separating the diamonds form the other material. This makes the process of diamond separation very effective for diamond plants.

DMS Powders’ Ferrosilicon includes the following properties and characteristics:

  • Medium Density: The medium density is directly controlled by the proportion of Ferrosilicon solids present in the medium. The medium density can be increased or reduced through adding either Ferrosilicon or water respectively.
  • Medium Viscosity: The medium viscosity is determined by the medium’s resistance to flow (the consistency). The higher the density, the higher the viscosity will be. /li>
  • Medium Stability: The medium stability can be described as the tendency of the solids in the medium to settle out. A high stability medium is due to a high concentration of solids, fine particles size in distribution, milled (irregular) shaped particles and the presence of low density contaminating solids.
  • Selection of the Medium: The operating density is the most essential factor to be taken into consideration when selecting Ferrosilicon Powder. The following factors also need to be considered: size of ore to be treated, sharpness of separation required, and costs. DMS Powders supplies a wide range of Ferrosilicon powders ideal for diamond plants – talk to our experienced team today to get the right products for your needs.

Heavy medium separation of diamonds

Heavy Medium Separation is a method used to separate diamonds from diamond bearing materials. Dense Media Separation has proven to be very successful to separate diamonds form other material and minerals, allowing for effective processes in DMS plants. Ferrosilicon is an essential part of the Heavy Medium Separation process, which is used to create a pulp with a specific density in which the separation will take place. Read more about the Heavy Medium Separation process, and what the process entails for the separation of diamonds. For more information about our Ferrosilicon for Heavy Medium Separation, contact DMS Powders today.
