About Dense Media Separation of Diamonds

Dense media separation is one of the two methods used for diamond recovery that makes use of powdered ferrosilicon. The powdered ferrosilicon is suspended in water, forming a liquid near the density of the diamonds. The diamond-bearing material is then added to the liquid in order for the separation process to start. The heavier minerals will then separate from the lighter material, for easy diamond recovery. This method if very efficient for diamond recovery, and is widely used in mineral mines across the world. DMS Powders has supplied many dense media separation plants with ferrosilicon powder for their application and process needs.

There are different types and grades of ferrosilicon products, as supplied by DMS Powders. The different grades have different physical properties and attributes, which ultimately determine in-circuit behaviour during the separation process. It is extremely important that these properties are appropriately matched to the type of dense medium process being applied and the nature of the required separation.

Producers of Ferrosilicon of different grades

DMS Powders produce Milled and Atomised Ferrosilicon products in different grades. Different processes require different grades of Ferrosilicon in order to achieve the best results. The grade of Ferrosilicon is determined by the Silicon content of the final products, as well as the physical properties of the Ferrosilicon. Different grades of Ferrosilicon will thus have different properties and in circuit behaviour, which needs to be considered when selecting a Ferrosilicon grade.

The properties of ferrosilicon manufactured by DMS Powders include medium Density, Viscosity and Stability, which are all interrelated. This is determined by the physical properties of the Ferrosilicon powder (such as particle size and shape), which is stringently managed in the Ferrosilicon production process. Read more about the Density, Viscosity and Stability, which are used as general guidelines to select the right Ferrosilicon grade for your specific process.

Producers of Ferrosilicon for other applications

Ferrosilicon is not only used in the Dense Media Separation of diamonds, but is also used in a number of other industrial applications, that require different grades. As leading Ferrosilicon producers, you will find a selection of Ferrosilicon products suitable for different application needs. Some other Ferrosilicon uses include:

• The deoxidising of steel
• The manufacturing of Magnesium in the Pidgeon process
• Heavy media separation process of metal and minerals
• Used in arc welding
• The electric industry uses Ferrosilicon as a source of pure silicon
• The manufacturing of Silicon Copper and more.

Our ferrosilicon products

DMS Powders produces two types of ferrosilicon products, including:

• Atomised ferrosilicon: This is a specialised powdered atomised ferrosilicon product which is produced in the process of melting high purity ferrosilicon with scrap and casting into a high-pressure water jet. This high-pressure water atomisation results in a fine particle distribution, which is then separated and classified according to grade.
• Milled ferrosilicon: Our Milled Ferrosilicon product is created by means of a two-step process which includes melting and milling, and the product is also screened and classified once cooled.
