As near-surface oxide orebodies are depleted, mines are having to process deeper sulfide ores that are lower in metal grade and metallurgically more complex. Modern technologies that are simple, cost effective and environmentally sound are required for their extraction. In many cases, bioleaching is the most suitable process.

Completed Projects

In the past 25 years, Mintek’s Biotechnology Division has been involved in a number of significant research projects, as well as the demonstration and commercial-scale implementation of our major technologies.
