Ferrosilicon for Diamond Processing – DMS Powders

Diamond processing is a multi-phase process that involves a number of different process stages. One of the initial stages requires the separation of the diamond from diamond-bearing material. A process called dense media separation is used, which uses the laws of gravity to easily and effectively separate diamonds and other minerals from the mineral bearing material.

DMS Powders is a producer of Ferrosilicon powders, which is used in the process of Dense Media Separation. Read more below about the use of Ferrosilicon in diamond processing plants, or contact DMS Powders today to order your Ferrosilicon products.

Milled FeSi: 65D, 100D, 150D, 270D, 270F

The use of Ferrosilicon in Diamond Processing Plants

Dense / heavy medium separation also referred to as the sink-and-float process, is widely used in mineral / diamond processing plants to effectively separate diamonds and minerals from other material. A medium is made in a gravity separator tank (Dense Media Cyclone), which is a mixture of Ferrosilicon powder and water, until it reaches a very specific density that will facilitate the separation of diamonds from other material. This density is usually very close to the density of diamonds for effective results. The diamond-bearing material is then submerged in the mixture, to initiate the gravity separation process. The Dense Media Cyclone will allow the heavier material to sink to the bottom of the tank, while lighter material floats at the top. This effective method will thus separate materials with different densities, and prepare the minerals for further processing.

Types of Ferrosilicon Powders produced by DMS Powders

DMS Powders produces two main types of Ferrosilicon, namely Atomised and Milled Ferrosilicon. Atomised Ferrosilicon possesses a spherical shape, where Milled Ferrosilicon is more angularly shaped, with slight differences in the production process. You can order the following Ferrosilicon products from DMS Powders to meet your mineral processing or other needs:

Atomised Ferrosilicon: Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70
Milled Ferrosilicon: 65D, 100D, 150D, 270D, 270F

About Ferrosilicon produced by DMS Powders

DMS Powders is a producer of Ferrosilicon, which is a ferroalloy, a chemical composition of iron and silicon. Ferrosilicon is produced by reduction of silica or sand with coke (fuel) in presence of iron.

Ferrosilicon produced by DMS Powders contain 14% – 16% Silicon (by weight) with a Relative Density of 6.8 – 7.1.

DMS Powders supplies a wide range of Ferrosilicon grades for dense media separation (DMS) in diamond processing. Different properties and characteristics of Ferrosilicon includes:

Medium Density: The proportion of Ferrosilicon solids present in the medium directly controls the medium density, which 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

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: With such a diverse range of Ferrosilicon produced by DMS Powders, it is important to select the correct grade of medium for the specific separation application. The following aspects in should be considered, in density of separation required, size of ore to be treated, sharpness of separation required, and costs.

It has been established that the use of Ferrosilicon is a simple and very effective product for use in dense medium separation (DMS), and specifically in the diamond processing industry – on the condition that the right grade is selected for the specific application.
