    A transformation process occurs among the various sulfur species, in which the sulfur is in different oxidation states depending on the potential of leaching solution. As sulfide begins to oxidize toward sulfate, it will first generate polysulfides with different chain lengths and then oxysulfide species such as thiosulfate and polythionates.
