The WhISPER project

The aim of WhISPER (Waterless Iron Silicate Production with Energy Recovery) is to develop a new iron silicate produced with the atomisation technology while evaluating and demonstrating the new properties of the material for improved commercial applications.
The project led by Atlantic Copper, will enable an optimal use of raw materials within Europe and will contribute to European Commission’s current strategy on Circular Economy.

Main benefits

The air atomization process will improve the Circularity of the Pyrometalurgical production of copper in Europe:

Up to 35% water saving of the global consumption of the plant,

Up to 50% reduction of the energy consumption of the slag processing line,

Improvement of copper slag quality to be used in new applications in building & construction sector.
