What impact will the EMILI project have on road traffic around the concentration site?

Road traffic will be limited thanks to the use of rail.

Around 15 HGVs a day will be needed to transport equipment and certain products used in the concentration processes.

Will you use chemicals in the concentration stage?

Yes. The use of certain chemicals will be necessary (sulphuric acid, amine collectors for mineral flotation and anti-foaming agents).

The processes implemented during the concentration stage are commonly used in a number of industries (pharmaceuticals, water treatment, etc.).
