based on thiosulphate leaching and resin in pulp

It was observed in all the pilot plant campaigns that an additional 0.1 to 0.3 g/t gold was leached from the ore dur- ing RIP. This gold could not be leached by simply extending the leaching time, indicating that even the gold thiosulphate complex is weakly adsorbed on strongly preg-robbing ores. Thus, a resin-in-pulp process...
