01/08/2017· Effect of galena on thiosulfate leaching of gold in previous studies. Obviously, the presence of galena was not favorable for gold leaching with thiosulfate (AlonsoGómez and Lapidus, 2009, Feng and van Deventer, 2003, Chen, 2008) but the detrimental effect mechanism of galena on gold leaching with thiosulfate is studied inadequately.

There is an old method, called the Parkes process, which was used to separate silver (and gold) from lead. The argentiferous galena is first reduced to metallic lead, Then zinc is added to the molten lead, The silver is much more soluble in the zinc. The zinc rises to the surface, taking most of the silver with it.
