What Mintek does

Mintek, founded in 1934 and headquartered in Randburg, Johannesburg, is South Africa's national mineral research organisation and one of the world's longest-established technology organisations specialising in mineral processing, extractive metallurgy, and related fields. Its core capabilities span hydrometallurgy, biometallurgy, pyrometallurgy, mineralogy, analytical chemistry, and advanced materials, organised into three operating clusters: Mineral Processing & Characterisation, Extractive Metallurgy, and Mining, Materials & Automation. The organisation operates world-class pilot-scale infrastructure used to develop, validate, and deploy proprietary metallurgical technologies, most notably the Floatstar flotation system and the Cynoprobe base metal and gold extraction technology, both of which are deployed across multiple African nations.

Mintek's revenue is generated through three primary streams: contract research and specialised services for mining industry and government clients, technology transfer and licensing of proprietary metallurgical processes, and product sales (principally the PhilaTest HIV 1/2 rapid diagnostic test kit manufactured under the DSI/Mintek Nanotechnology Innovation Centre). Its customer base is concentrated in the mining industry, governments and national institutions, and the critical minerals sector (rare earth elements, PGMs, battery minerals), with a secondary footprint in healthcare diagnostics. Products and services are deployed in over 40 countries globally, with active collaborations extending from across sub-Saharan Africa into India.

The organisation serves South Africa's national interest through mineral processing R&D and technology transfer, and is increasingly positioning itself around the country's Critical Minerals and Metals Strategy — targeting downstream beneficiation beyond pit-to-port exports. Its state-owned, non-listed status means it operates outside conventional private capital structures, with funding sourced primarily from government allocation, contract research, and commercial licensing rather than equity markets.
