sulphate ions in pressure oxidation and biooxidation. The iron component is oxidised to the trivalent state and forms solid compounds such as haematite (roasting), basic iron sulphate or jarosite (pressure oxidation and biooxidation) and soluble compounds such as ferric sulphate (pressure oxidation and biooxidation). Ultrafine grinding is a ...

Autoclave Reactor is the key equipment for pressure leaching. It is high resistant to high temperature, strong acidity and longterm wearing. The reactor can also resist to working media with high F/Cl content.

Pressure oxidation (POX) leaching has been commercially applied to refractory gold ores since the 1980s. In the process, sulphide material is oxidised and dissolved in order to release the gold encapsulated in the sulphide matrix, making the gold available for further recovery. . sc553 pressure roller fusing iamp over temp; pressure oxidation .
