Who
Should Attend
This one day course is intended for scientists, engineers,
plant operating engineers, environmental engineers,
and managers who are involved in the processing
of arsenic bearing materials and its disposal in the
non-ferrous metal industry. It is highly recommended
not only for environmental professionals seeking a first
introduction to arsenic metallurgy, but also those with
prior but dated or limited experience.
Course Overview
Arsenic has been a problem associated with the extraction
of non-ferrous metals and precious metals. Until 20
years ago, arsenic tri oxide from the non-ferrous industry
was used as chromated copper arsenate as protection for
lumber. However, with the banning of its use for domestic
lumber in USA, its usage has decreased considerably. This
has raised environmental concern about its safe disposal
during the processing of base and precious metals.
This one day interactive course will include:
-
Role and distribution of arsenic during processing
of base metals and precious metals.
-
Treatment of As-containing byproduct streams for
As removal.
-
Fixing of arsenic in slags; Bevill Amendment.
-
Treatment of aqueous effluents for heavy metals’ removal including arsenic.
-
Aqueous chemistry of Arsenic
-
Chemistry of Waste Water Treatment with special
reference to Arsenic Removal.
-
Formation and Stability of Arsenic Compounds–Fe/As coprecipitates and Scorodite
-
Concluding Remarks.
