| COURSE IN
PYROMETALLURGY
OBJECTIVES
In South Africa and around the world, there is a chronic shortage of
Metallurgical Engineers with a strong background in the field of pyrometallurgy
and/or high temperature processing. In order to be able to alleviate this
problem the six postgraduate courses described briefly here has been designed to
allow those who work or wish to work in the pyrometallurgy field, to upgrade and
broaden their knowledge. The courses are knowledge based and do not necessarily
involve technology transfer and thus the aim is to produce qualified people who
can feel more at home in the pyrometallurgy field.
WHO
SHOULD
ATTEND
Process engineers from the contracting and consulting companies and research
organizations involved in pyrometallurgical processes. · Plant metallurgists
and managers responsible for high temperature processes. · Consulting
metallurgists involved in new projects and flowsheet development in
pyrometallurgy field. · Graduates engineers and diplomates and science
graduates whose backgrounds did not adequately cover both fundamental and more
applied topics in pyrometallugy and who are interested in improving their
knowledge.
· Engineers, diplomates and scientists in refractory manufacture.
The lecturers will presume the delegates have some tertiary education.
