Measurement And Control Solutions

The Measurement and Control division has developed a range of specific Advanced Process Control Solutions that are implemented on Mintek’s process control platform, StarCS. Advanced stabilisation and optimisation control has been developed for Milling, Flotation, Smelting and Gold Leaching.


Carbon activity must be monitored on a continuous basis during the gold extraction process to minimise dissolved gold losses, increase recovery, and to ensure optimum plant operation. The CAA (Carbon Activity Analyser) is a computer-based, automated instrument that facilitates the rapid and reliable determination of carbon activity.

The CAA provides independent, simultaneous measurements of the activity of up to four samples of carbon and a dynamic comparison of sample adsorption against a defined threshold curve. The CAA is significantly cost-effective since it requires minimal maintenance.


  • Simple, rapid and reliable determination of carbon activity.
  • Independent, simultaneous measurements of four samples.
  • Dynamic comparison of sample adsorption against defined “threshold” curves.
  • Sample measurement time of one hour.
  • Human error eliminated.
  • Significant time and cost reduction.
  • No need for a highly skilled operator. Operator training is provided in the software supplied with the instrument.
  • Minimum maintenance.
