A recovery system for precious metal particles in wash solutions includes a pair of filter elements and a pump mounted within a closed tank. The first filter is of relatively large pore size, and traps layer particles. The prefiltered liquid is collected within the tank. A pump is mounted within the tank, and drives the collected liquid and remaining particles through the second filter, which is of a small pore size chosen to trap the remaining particles. After passage through the second filter the wash water may be discarded.
