A plasma refining plant installed by Tetronics in Taiwan for Solar Applied Materials Technology Corp. has successfully achieved full operational status.
The plant will recover precious metals (PM) and platinum group metals (PGM) from spent catalyst and electronic waste streams. The plasma refining plant has demonstrated industry leading levels of technical recovery of PGM from spent industrial catalysts.
A global leader in plasma arc technology for metal recovery and hazardous waste treatment applications, Tetronics announced that its customer and partner, Solar Applied Materials Technology Corp. has confirmed full operational status of its plasma plant where the Tetronics technology, capable of recovering >98% of PGMs from spent catalysts, will be used to process and recover PMs and PGMs from spent catalysts and electronic waste.
This brings Tetronics’ plasma technology global installed base to 86 for applications including resource recovery and hazardous waste treatment, reinforcing the company’s position as a global market leader of plasma arc technology.
The Solar plasma plant achieved full licensed operational status following the successful completion of the Final Acceptance Test (FAT). The plasma plant will process up to 1,850 tonnes per year of spent catalysts, producing 120,000 troy oz of PGM based on typical automotive catalysts profiles.
Tetronics’ patented plasma technology combines high technical recovery rates and operational flexibility, with low environmental impact and cost base. The process chemistry in the technology is designed to smelt and preferentially separate the PMs from less valuable material, which is vitrified into an inert, safe usable product called Plasmarok in a single processing step. The process will also destroy any hazardous organics contained within the material.
