Mintek is South Africa’s national mineral research organisation and it is one of the world’s leading technology organisations specialising in mineral processing, extractive metallurgy and related areas. Working closely with industry and other R&D institutions, Mintek provides service testwork, process development and optimisation, consulting and innovative products to clients worldwide.
Mintek is an autonomous statutory organisation which reports to the Minister of Mineral Resources. About 30 per cent of the annual budget of R390 million is funded by the State Science Vote, with the balance provided by contract R&D, sales of products and services, technology licensing agreements, and joint-venture private sector companies.
Mintek has about 780 permanent staff members, over half of whom are scientists, engineers and other technical R&D specialists.
Mintek as a company operates within the complex and challenging economic and social landscape that characterises South Africa. Added to this responsibility is the task of operating effectively in the global environment, and satisfying the demands of a knowledgeable customer base.
Our technical programmes are aimed at generating high economic returns for the national and regional economies. Our social programmes focus on skills development and educational initiatives. An important target is the nurturing of self-sustaining local economies in areas of South Africa where smaller minerals extraction and beneficiation enterprises have the capability to generate broad-based employment and wealth.
The Mintek corporate structure is headed by a Board, which includes a Chairperson and Mintek’s CEO, plus an additional six to nine other members. The Chairperson is appointed by the Minister of Mineral Resources.
Mintek’s Board of Directors bring a significant technical and business expertise to the company, ensuring that both the technical and the social targets will have a meaningful impact on the present and future economy of South Africa.
The CEO of Mintek is supported by the Executive Management team and 14 Divisional Managers.
