- •
The process of alkaline pressure oxidation–thiosulfate leaching was developed.
- •
Sulfide minerals were effectively oxidized by alkaline pressure oxidation.
- •
The reagent dosage of alkaline pressure oxidation was less than stoichiometric.
- •
The secondary encapsulation of gold was relieved during alkaline pressure oxidation.
- •
The environmental risk of this developed leaching process was very low.
