About the project

The Aeris project will modernize the Horne Smelter by building a brand new state-of-the-art section of the plant. These major investments, totalling around $500m, should enable us to become one of the most efficient copper smelters in the world in terms of atmospheric emissions.

The Aeris project includes the modernization of the converter and anode sectors using new technology developed by our in-house teams, a new casting wheel system and a high-capacity dust collector.

According to our current projections, the Aeris project should reduce the average annual concentration of arsenic in ambient air to 3 ng/m3 or less for approximately 84% of Rouyn-Noranda's urban perimeter, 7 ng/m3 or less for approximately 97% of the urban perimeter and 15 ng/m3 at the legal station located at the boundary of our property, following the commissioning of the project.

Project objectives

  • Reduce atmospheric emissions
  • Reduce energy consumption and greenhouse gas emissions
  • Increase recycling of copper and critical metals
