Consumption & discharges

Prélévements et rejets

The use of water is central to most of our operations: for processing, dust suppression and cooling.

We recycle water wherever possible, and our global standards require operations to periodically review opportunities for water re-use. Our global standards require our operations to identify and characterize all water discharge sources, and as a minimum to ensure that any required permits are in place and adhered to.

Our activities produce relatively small quantities of industrial waste. This is because minerals are mainly converted by mechanical (e.g. grinding) and physical (e.g. density separation) processes.

We monitor the rollout of our three-year plan for Sustainable Development through performance indicators defined by internal experts.

Energy & emissions

For several years, we have implemented action programs to improve the energy efficiency of its industrial activities and reduce its greenhouse gas emissions.

Restoration & Biodiversity

We strive to lessen negative impacts of our mining and processing activities on biodiversity.


Constantly improving the environmental impact of our products and processes is a priority for our R&D programs.
