As the percentage of matte processed through the new converter increases to
approach 100% in 2002, the amounts of pollutants released will decrease.
Noranda reports that this would increase the fixation of incoming sulphur to 90%.
The absolute amount of sulphur dioxide released represents a reduction of
approximately 90% of the 1980 releases (i.e., 552,000 tonnes). Noranda also
reported a reduction of particulate emissions by 50% from current levels. This is
a cost effective and environmentally positive next step. It is likely that the
emissions reductions of total particulate matter and CEPA-toxics would be much
greater than 50%, depending on the extent to which the equipment is modified.
This approach is summarized in Table 76.
Table 75 provides a summary of the potential releases from the Noranda Horne
Smelter in 2008 and beyond 2008.
