What we do
Sepro Urban Mining has leveraged decades of experience in the mineral recovery industry to develop specialized equipment and methods to maximize metal recovery in urban environments. Our urban mining solutions reduce processing costs associated with urban metal recovery from electronic scrap, cables, household recycling and incinerator bottom ash.
E-Waste
Sepro has a number of different methods for the recovery of valuable metals from e-waste depending on the type, volume and composition of material to process. Solutions include physical separation as well as hydrometallurgical and pyrometallurgical processes.
Incinerator Bottom Ash
Sepro has developed proprietary systems for the recovery of precious metals and other high-value elements from incinerator bottom ash. Specifically, we are experts at the recovery of metals smaller than 4mm, while traditional technologies struggle for effective recovery.
Custom Solutions
Sepro has developed many custom solutions for the recovery of precious metals and high value components of urban waste streams. We have the knowledge to develop innovative processes from first principles, and the experience to apply those processes at the industrial scale.
Case Studies
Wet IBA Processing
Learn more about Sepro’s innovative wet process for recovery of fine metals from incinerator bottom ash.
GO
E-Waste pyrolysis
Learn more about pyrolysis and gravity recovery of metals from e-waste. This is particularly helpful when gravity concentration and leaching are not ideal options.
GO
Leaded glass separation
Older TVs and computers with CRT displays can contain up to 40% lead oxide. Learn more about leaded glass separation via dense media separation.
GODid you know?
Incinerator bottom ash from waste-to-energy facilities often has a higher percentage of gold than the world’s highest-grade gold mines!
Possibilities and Limitations in Wet Processing of IBA
This paper includes a thorough overview of the challenges of recovering precious and base metals from IBA, as well as the application of gravity concentration for recovering metals in the fine size fraction.
