By choosing the correct grade of atomized and milled FeSi, the efficiency of your DMS / HMS plant can be improved, and therefore increasing the overall efficiency of the beneficiation process.

Milled Ferro Silicon 15# is a magnetic ferrosilicon produced in electric arc furnaces and subsequently milled to the size ranges required. In addition, Milled Ferro Silicon contains aluminum and titanium which enhances its resistance to corrosion.

DMS Powders business started as part of Amcor in 1949 with the production of Milled Ferrosilicon (FeSi) for use in Dense Medium Separation in the extraction of diamonds. In the 1950’s the production facilities were relocated to the current site near Meyerton.

We produce corrosion resistant milled ferro silicon for heavy media separation to the mining and scrap sectors. Grades include 65D, 100D, 150D & 270D.

DMS Powders is the leading supplier of both milled and atomised dense-media ferrosilicon. Our consistently high-quality ferrosilicon ensures maximum separation efficiency and media recoverability. Powders for diamond recovery, iron ore, scrap-metal recycling and manganese ore

Sinoferro is a China-based supplier of dense medium ferrosilicon for heavy medium separation processing (HMS) or dense medium separation processing (DMS) including both atomised and milled ferrosilicon 15%, and also milled brown fused alumina and atomised ferrosilicon 45% for welding applications.

After the ferrosilicon particles are screened to remove any oversize fragments, these fragments are then milled to create products called Milled FeSi (Ferrosilicon). DMS Powders offers Milled FeSi in the following grades: 65D, 100D, 150D, 270D, and 270F.
