Dense Media Separation Powders (Pty) Ltd

The production of Milled Ferrosilicon (FeSi) in South Africa dates back to 1949 for use in the Dense Medium Separation of diamonds.

This was also the early beginning of DMS Powders, trading as Amcor at the time. The production facility relocated to Meyerton in the 1950s with the Atomized Ferrosilicon production facility being commissioned in 1967. In 1975, Amcor merged with SA Manganese and started trading as Samancor. A stand alone business entity for Ferrosilicon was created in 2000 with the formation of DMS Powders, a division of Samancor.

In April 2006, an independent company Dense Medium Separation Powders (Pty) Ltd was established under new ownership as a fully Black Economic Empowered company as defined by the South African Black Economic Empowerment Act of 2004.

This commitment not only benefits our society, but also bears fruit within our company as human resource development and employment equity ensures a highly skilled and diversified workforce.
Our production expertise is coupled with experienced product technical support, long-term customer relationships and an intimate knowledge of global logistics.
