Abstract
The electrodeposition and recovery of gold from spent electroplating bath solutions using a graphite cloth electrode in a flow-through cell is described. Optimized conditions of flow rate, current densities, screen potentials and additives were established to achieve high-percentage recoveries and good separation of the Au from admixtures of base metals (Cu, Cd). The results are sufficiently encouraging to serve as the basis for a scaled-up process.
