Silver Recovery and Reactive Materials

Silver Recovery and Reactive Materials » Electrowinning and
Application: As a cathode material in electrowinning cells used to recover gold and other precious metals from mining slurries.

Benefits: The performance of low carbon steel wool and stainless steel wool in electrowinning have the following benefits:
  • Low carbon steel is most effective and has high strength properties while Stainless wool is reusable
  • High surface area
  • Offer a consistently high yield
  • Consistent sized fibers (60 to 130 microns

  • 4" continuous bulk reels, available in standard 5 lbs or 20 lbs increments
  • Needled batt up to 2.7 meters (105 inches)
  • Special die cut shapes or assembled panels of material is also available in various basis weights
