(University of Pretoria, 2023)Froth flotation models that are developed for circuit design applications are often not suitable for model-based dynamic control and optimisation applications. For real-time control and optimisation applications dynamic ...
-
(University of Pretoria, 2023)This work builds on existing observable dynamic models of froth flotation circuits, aimed at on-line parameter estimation and model-based control. The models are analysed and two main limitations are identified and ...
-
(University of Pretoria, 2018)A run-of-mine (ROM) ore milling circuit is primarily used to grind incoming ore containing precious metals to a powder fine enough to liberate the valuable minerals contained therein. The ground ore has a product particle ...
-
(University of Pretoria, 2023-11-01)Model-based controllers often extend improved performance to mineral processing plants by leveraging predictive models to account for system dynamics, handling constraints, adapting to changing conditions, and optimizing ...
-
(University of Pretoria, 2021)The thesis is developed in three sections to realise the objectives of using the inherent storage capacity in industrial gas headers to mitigate pollution due to gas emissions and improve the flow stability of consumers. The ...

(University of Pretoria, 2015)A run-of-mine ore milling circuit is primarily used to grind incoming ore containing precious metals to a particle size smaller than a specification size. A traditional run-of-mine (ROM) ore single-stage closed milling ...
-
(University of Pretoria, 2023)Auto-tuning of multi-input multi-output (MIMO) controllers of a bulk tailing treatment (BTT) surge tank is presented. Two controllers are selected for optimisation. The first controller is a decentralised proportional-integral ...

(University of Pretoria, 2023)In this dissertation, a flotation circuit is controlled in simulation using an extremum seeking control (ESC) approach to optimize the flotation performance of the circuit using peak air recovery. Flotation is a separation ...
