Mintek

Mintek is a South African state-owned science and technology organisation specialising in mineral processing, extractive metallurgy and related technologies. The entity operates as a statutory research organisation under the Department of Science and Innovation, with a mandate to serve the minerals industry through applied research, development and technology transfer. Mintek is headquartered in Randburg, Johannesburg, and maintains pilot-plant facilities and laboratories that support the beneficiation of South Africa's mineral resources. The organisation conducts research across a range of metallurgical processes, including pyrometallurgy, hydrometallurgy, electrometallurgy and mineral processing. Its work spans base metals, precious metals, platinum-group metals, ferrous metals and increasingly critical minerals such as rare earth elements. Mintek provides technical services to mining companies, smelters and refiners, and develops proprietary technologies for licensing. Notable innovations include the Mintek Thermal Magnesium Process and various leaching and recovery techniques. The organisation also offers analytical services, process design, feasibility studies and training. Mintek collaborates with industry, universities and international research bodies to advance mineral technology and support the competitiveness of South Africa's mining sector. It was established in 1934 as the National Institute for Metallurgy and was reconstituted as Mintek in 1989.
