One of Mintek's greatest strengths is its ability to take concepts from the small laboratory scale to full pilot-plant studies, with particular emphasis on integrating the various unit operations into a balanced flowsheet. In addition to testwork at Mintek, pilot plants are often run on-site in industry for extended periods. Milling and sample preparation. Comprehensive facilities exist for conventional, autogenous, and stirred milling . These facilities are available for the evaluation of circuit design and optimization.
Physical separation processes.
The techniques used include gravity, magnetic, and electrostatic separation. A full range of equipment is available for conventional and pressure leaching, and filtration. Specialized equipment has been developed for process development, plant optimization studies and troubleshooting. A particular strength is the ability to conduct testwork with full commercial-sized cathodes. Large pilot plants have been erected and run at clients' sites for process development and optimization studies.
