    A simplified model for Anglo Platinum's continuous secondary leach in the base metals' refinery
    (2010) Erasmus, Deborah
    An Excel-based mathematical model simulating the Base Metal's Refinery Secondary Leach operation is developed in this thesis. Fundamental building blocks of batch leach data, equipment specifications, process conditions and feed characteristics are used to develop the model. The aim of which is to develop a tool to verify actual plant performance against theoretical performance and assist with troubleshooting in the plant or serve as a basis for future autoclave design. In the present study the model is specifically used to investigate the cause of the reduced leach efficiencies that the plant is experiencing.
