Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation
Emerging pressure oxidation processes that can be used to treat gold-bearing arsenopyrite include a calcium chloride-oxygen leaching procedure (9) and the arseno process (10). The two procedures are unique in that mild temperatures ( < 115° C) and pressures ( < 100 psig O2) can be used to effect the oxidation of sulfide minerals.

(DOC) GOLD MINING | Arief Syara
Thiosulfate Amalgamation is one of the oldest processes available. It relies upon the contact of ore with mercury to form a gold-mercury amalgam. This process is strongly out of favor with the major mining companies, due to the extremely toxic nature of mercury and the processes inferior performance when compared to the available alternatives.

Another problem with pressure and bacterial leaching, which use either high temperature and pressure in titanium autoclaves, or bacteria that are required to be maintained under strict conditions, is the requirement for a high level of operation and support. Therefore, there is a hesitancy by mining companies to use them in remote areas.
