ABSTRACT:
The present invention relates to a process for the separation of gold from particulate material containing gold, which comprises introducing a hydrophobic liquid, a non-gold particulate hydrophobic bulking material and particulate, gold containing material into an aqueous liquid so that the hydrophobic liquid becomes associated with the gold and, in conjunction with the non-gold particulate hydrophobic material, forms gold bearing agglomerates bonded by the hydrophobic liquid, and separating the gold bearing agglomerates from the aqueous liquid.
