New insights into the mechanism of pyrite oxidation in
In the actual leaching process of gold ore, when the pyrite was originally present or intentionally added, pyrite can promote or hinder the leaching of gold from its ores in the Cu 2+ –NH 3 –S 2 O 3 2− system, mainly by catalysing thiosulphate decomposition or consumption [17]. A model study has shown pyrite can be able to catalyse the ...
