A learner achieving this qualification will be qualified to monitor and control a mineral processing plant. This is the third qualification in the learning pathway for Mineral Processing. A learner would proceed from this qualification to a National Diploma or Degree in Extraction Metallurgy or Chemical engineering.

such as plant design and optimization, operational optimization, control system de-sign and verification,as well as operator training. Nowadays, models play an impor-tant role in the planning and operation of mineral processing plants, as described in [4]. Basically, each model representing a process has an associated set of variables,
