Air quality

Our goals include optimizing our gas capture system, materials storage, and internal road maintenance to prevent wind from spreading the dust. To do this, we purchased a vacuum truck and apply dust suppressants as required. Concentrates are stored indoors as much as possible, which is why we have installed several domes at the site, in addition to constructing a concentrate storage building.

Our plan to reduce air emissions

2020 was a pivotal year for our environmental performance.

After implementing the last project for our second remediation certificate, we found a significant improvement in our air emissions, particularly arsenic.

Improvements in the anode furnace sector, optimization of the casting wheel hood, and the addition of a new duct to the dust collection system led to significantly lower arsenic emissions recorded at the statutory station during the year.

While these results are encouraging, we recognize that more work needs to be done, and that is why we continue to work with government authorities and all stakeholders to implement innovative, effective solutions to reduce our air emissions.

VELOX pilot project

The VELOX pilot project is the flagship project of our air emissions reduction plan. This pilot project involves an upgrade of our converters for the purpose of testing a new technology that does not yet exist in the copper industry. This technology has the potential to significantly reduce our air emissions.

If we can show the technical and economic feasibility of deploying the VELOX technology on a large scale, we may be able to implement the PHENIX project. This project would reduce the percentage of arsenic emissions at the statutory station by 10% to 15%. It would also reduce the greenhouse gas emissions associated with our process and increase our capacity to process recycled materials by about 15%.
