Comparing it with the standard electrode potential of nitric acid,the reason of dissolution of HgS in aqua regia was quantitatively revealed,and this is that the high concentration of chloride ions reduces the reduction potential of sulfur in HgS,thus raising the reducing power of HgS rather than that the oxidizing power.

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

M/s. The following dimensionless relationships were obtained: Sh=2+0.073Re〓Sc〓〓〓 The desulphurization process by powder injection and blowing in RH refining of molten steel and its mechanism have been considered and analyzed. Based on the tworesistance mass transfer theory and the mass balance of sulphur in the system, a kinetic model for the process has been developed. The related parameters of the model have been reasonably determined. Modeling and calculations for the process by injecting and blowing the lime based powder flux under the assumed operating modes in a RH degasser of 300t capacity have been carried out using the model.

Further more researches indicate that it is just the bacteria adhereing that decrease surface free energy of pyrite and reduce the effect of catching pyrite by catching medicament. But the desulfurization is not the oxidation action of microbial or decreasing its hydrophile of pyrite.
