gold leaching with chlorine plant

Oct 10, 2019· In the leaching experiments,gold leaching in “typical” aggressive chloride leaching mediawas compared against less aggressive chloride solutions. Leaching experiments in chloride-bromide media (tests 1–8) and in chloride media without bromide addition (tests 9–19) were carried out at Outotec Research Center, Pori, Finland. The parameters observed in the leaching series were solid …
