Plasma Recycling System for Metal Recovery - Metal
ArcFume is a metallurgical plasma based process for treatment of complex industrial waste. With a high yield, it recovers valuable metals as zinc, lead, silver, copper, germanium and indium. Handling of by-products is an important step for metal smelters towards higher metal yield and less waste. By introducing the plasma based ArcFume process, they are moving towards electrification of the process flow sheet.
Examples of complex materials are jarosite, goethite, paragoethite, or hematite formed after electrolytic recovery in zinc production process. In the residues, to some extent zinc and lead follows along with other minor elements such as silver, indium and germanium. The residues are typically landfilled after a stabilization process, but due to the content of valuable metals it is highly relevant to recover the metals.
ScanArc has performed excessive test campaigns for Boliden Kokkola Smelters to treat the residues in ArcFume process for metal extraction. After metal extraction, a glassy mineral product with good environmental properties possible to use in cement and geopolymer applications is produced.
