Earlier this month, Applications Specialist Daniel Parvaz attended Physical Separation 2019, a key industrial conference organised by Minerals Engineering International to talk about our continuous high voltage fragmentation system operating at the SAIDEF plant in Switzerland.
The first part of the conference showcased new and novel technological developments in the comminution industry,and SELFRAG’s high voltage pulse processing method was featured alongside other experimental methods such as microwave treatment of ores.
This Scoria system used in the SAIDEF plant is the first of its kind and has led to many additional developments in the processing of incinerator bottom ash (IBA). Disposal of IBA, the solid residues of municipal waste incineration is a challenge, as the metal content can be up to 12%, classing it as a ‘reactive’ waste, increasing landfill costs. Metal recovery decontaminates and reduces the volume to landfill and generates additional revenue.
IBA is a difficult material to work with, being heterogeneous with unique and problematic components such as organics, fabrics, wires and cables which pose a unique challenge to mineral processing. During the operation of the plant, these challenges have been identified and overcome, to vastly improve the system, and these technological developments will be carried forwards into future SELFRAG systems – after processing IBA, concrete and mineral ores will be easy!
Conferences such as Physical Separation are invaluable in demonstrating SELFRAG’s technology and establishing our niche in the crushing market. In addition to meeting with colleagues and collaborators from across the globe, such as Rui Sousa from the FAME Project, we gained new ideas, and potential collaborations for the future!
