  • Platinum group metal recovery from spent catalysts case study

    The Challenge Catalyst wastes, including automotive catalytic converters and industrial catalysts, contain Precious Metals and specifically Platinum Group Metals (PGMs), which are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction and refining from primary sources. Furuya Metal Co. Ltd., ...

  • Pilot test of pollution control and metal resource recovery for acid mine drainage

    The study was undertaken in order to recover the metal resources from acid mine drainage (AMD). A 300 m3/d continuous system was designed and fractional precipitation technology employed for the main metals Fe, Cu, Zn, and Mn recovery. The system was operated for six months using actual AMD in situ. The chemicals' input and also the retention time was optimized. Furthermore, the ...

  • Development of a packed-bed reactor for the recovery of metals from industrial wastewaters

    Affinity separation is becoming well established for the purification and recovery of metals from industrial wastewaters. Although the method has been successfully applied on a bench-scale, there is a need for reaction engineering studies to scale-up the process for use in large-scale wastewater purification and recovery of valuable metals. In this study, a pilot-scale packed-bed reactor has been ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Austin AI QXR-M – Technology to improve metal recovery from non-ferrous residues

    Existing technology has been used for some time to separate light non-ferrous alloys from heavier non-ferrous alloys; however, over the past three years, there is a significant added value in performing additional separations to recover specific high dollar alloys. Examples of such are separating pure copper from copper alloys (brass and bronze) or wrought from cast aluminum. The only way to do ...

Duncan Refining and Recycling's (DR2) President, David Nichols, made the decision to ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • Titanium Scrap Metal Processing

    Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, ...
