We developed the GRC Gold Recovery System especially to recover gold from grinding and polishing sludge, scraps, sweepings and ashes. As a matter of course the recovery of gold from solutions such as rinsing baths, polishing baths etc. is also possible
The GRC system consists of a completely new concept of a dissolution unit and an electrolytic cell. In one step, the precious metals can be recovered directly from the above mentioned waste.
Compared to the common method of boiling the sludge with aqua regia the GRC System either works with cyanide or cyanide-free.
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.
