Modelling and control of an autogenous mill using a state space methodology and neural networks
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Metallurgical processes are often high dimensional and non-linear making them
difficult to understand, model and control. Whereas the human eye has extensively
been used in discerning temporal patterns ...
The control of calcium and magnesium in a base metal sulphate leach solution
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: This thesis investigates the control of calcium and magnesium in a base metal
sulphate leach solution containing nickel and cobalt. The presence of calcium and
magnesium in the hydrometallurgical ...
The development of a one-dimensional quasi-steady state model for the desulphurisation process at Saldanha Steel
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: The pneumatic injection of reagent powder into molten iron has become
the preferred way to carry out iron and steel desulphurisation. It is
therefore essential to not only understand the thermodynamic ...
Investigating the effect of coarse particle addition on the measured rheological parameters of fine clay slurries
(Stellenbosch : Stellenbosch University, 2007-12)
ENGLISH ABSTRACT: Due to economic and environmental constraints mining operations are placed under
increasing pressure to effectively manage and operate tailings disposal operations.
Restrictions imposed on water usage ...
Multivariate nonlinear time series analysis of dynamic process systems
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: Physical systems encountered in process engineering are invariably ill-defined, multivariate,
and exhibit complex nonlinear dynamical behaviour. The increasing demands
for better process efficiency and ...
