Carbon and Resin Technologies for Gold Recovery SGS

In recent years, resin is replacing carbon as the gold recovery substrate of choice. SGS is the world leader in the development of this technology. The process used in resin recovery is similar to carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon grains.

Review of gold extraction from ores - ScienceDirect

The potential for resin-in-pulp (RIP) to replace CIP/CIL is discussed. The use of cyanide has generated environmental concerns because of its toxicity and therefore research on alternative gold recovery processes using non-toxic reagents is considered. The key candidates are: ammoniacal thiosulphate, thiourea and halide solutions.

The Resin-in-Pulp (RnP) technology for gold and base metals recovers metals directly from slurries. The technology works on the same principle as Carbon-in-Pulp (CIP), which is widely used for gold recovery in a process where soluble gold from the leached slurry is adsorbed (loaded) onto carbon or resin particles. The loaded adsorbent is then separated from the slurry via screening, and eluted ...
