Where We Operate

With the country's highest resource concentrations, Mpumalanga, Limpopo and the surrounding regions have been at the epicentre of local coal mining industry for decades. it's no surprise then that this is where Exxaro's mines can be found.

Exxaro created renewable-energy company Cennergi in 2012 and built two wind farms with a combined capacity of 229 MW in the Eastern Cape in 2016

Ferroalloys Ferrosilicon Plant

Exxaro’s FerroAlloys ferrosilicon plant was established in 1996. Two new plants were commissioned in 2014 and 2016 respectively in order to guarantee supply of up to 12 000 tonnes of superior quality gas atomised and milled ferrosilicon (FeSi) per annum. Over the last two decades, Exxaro has developed two groundbreaking processing technologies aimed at improving beneficiation processes and the recovery of mineral products from low grade stockpiles, in-situ resources and waste dumps in order to overcome global mining challenges such as depleting reserves and resource quality issues. A key component of both the Ultra High Dense Medium Separation (UHDMS) and Ultra Fine (UF) processing technologies is the high-quality gas atomised ferrosilicon produced at Exxaro FerroAlloys. Early commercialisation projects were conducted successfully in the iron ore industry with the support of Kumba Iron Ore, where Exxaro holds a 20% shareholding in its subsidiary, the Sishen Iron Ore Company. The UHDMS and UF processes are currently being commercialised across a number of other commodities with the intent of growing the market. The production of FeSi is therefore critical to Exxaro’s long-term growth and investment strategies.


Exxaro FerroAlloys is ISO 9001, ISO 14001 and OHSAS 18001 certified and adheres to strict control measures to ensure compliance with all quality, environmental and health and safety standards. In the six years since the original certification, Exxaro FerroAlloys has successfully met the criteria of surveillance and recertification audits conducted by an external certification body.
