Effect of lime additions and bulk chromium content on chromium deportment in smelter matte-slag systems
(Stellenbosch : Stellenbosch University, 2010-03)
ENGLISH ABSTRACT: More mining houses are turning their attention to the processing of ore mined from the UG2 reef. This is mainly due to the depletion of the Merensky reef or the low availability of ore from the Platreef. ...
The development of a simulative hybrid model for optimising the production of a high-carbon ferromanganese furnace.
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: A project was initially commenced for optimising the production output at a specific high-carbon ferromanganese furnace. Since operational difficulties were experienced in this furnace and with a lack ...
A generic, semi-empirical approach to the stochastic modelling of bath-type pyrometallurgical reactors
(Stellenbosch : University of Stellenbosch, 2004-03)
ENGLISH ABSTRACT: Bath type furnaces have become an established technology for the intensive smelting, converting and refining of primary and secondary raw materials. Since these furnaces normally have large inventories, ...
Chromium deportment in copper matte equilibrated with CrxO-containing slag
(Stellenbosch : University of Stellenbosch, 2006-03)
An understanding of the behaviour of chromium in mattes equilibrated with chrome-saturated slags is essential for the prediction and control of chromium deportment in these melts. The main ore reserves of South Africa’s ...
