MERIT Metal Recovery Intelligence

This module was developed in order to increase the metal recovery rate from incinerator bottom ash. Our technical innovation is based on a ballistic separation principle. A controlled air stream is used to intelligently remove the disruptive fine fraction of ash, without removing inherent valuable metals during the process. The complexity lies in the optimum adjustment of environmental parameters and process variables such as the airdrop trajectory and air velocity. Following this, the use of additional eddy-current separators ensures the best possible non-ferrous recovery rate from the remaining mineral fraction.
