(MERAF) for the Base Metals Smelting Sector - CCME

• Falconbridge Sudbury;
• Noranda Horne; and
• Noranda Gaspé.
It has been assumed that a 10% reduction in aggregate releases is possible from
other the sites not analyzed in detail.
The economic data presented is based on the sector as it was in 1998. It should
be noted that the sector has made various changes to processes and controls
since that time.
These changes include:
• Hudson Bay Mining and Smelting is commissioning a $30 million
improvement systems for gas handling in 2000/2001 which should
result in a 30% decrease in total particulate matter releases
• The “Stack Tap Hole” at Noranda Horne, which was used to discharge
secondary gases from the Noranda Reactor and the Noranda
Continuous Converter, is no longer functional as of May 2000. The
gases are now collected and treated through a baghouse with lime
injection and directed through the converter stack (“Stack #2”)
• Reductions in releases at Noranda Horne have occurred due to
increasing percentage of matte being processed through the Noranda
continuous converter, since 1998 reported data.
• On March 28, 2002, Noranda announced the permanent closure of its
Gaspé smelter effective April 30, 2002.
