Gold Recovery GRC

We developed the GRC Gold Recovery System especially to recover gold from grinding and polishing sludge, scraps, sweepings and ashes. It goes without saying that the recovery of gold from solutions such as rinsing baths, polishing baths etc. is a matter of course.

The GRC system consists of a completely new concept of an electrolytic cell where the recovery starts with the filtration of sludge in a reactor especially designed for this purpose.

Compared to the commonly used method of boiling the sludge, the GRC system uses aqua regia to achieve a much higher percentage of gold recovery. Another advantage of the GRC system is that the gold inside the reactor is dissolved at room temperature which reduces energy costs and prevents the emission of toxic gases so that a scrubber is not required.

Application areas for this unit: Advantages:
  • grinding sludge
  • polishing sludge
  • sweepings
  • ashes
  • bombing solutions
  • electroplating solutions
  • high metal deposition rate
  • recovery at room temperature
  • no corrosive/toxic gases
  • compact, space-saving design
  • easy handling
  • low running costs
  • easy removal of deposited metals
