The results of these tests, presented two arsenic pyrite oxidation most likely related to the mechanism :( 1) directly under the oxidation action of oxygen, (2) oxidation under action of the ion Fe (Ⅲ). At this time, the action of oxygen enables Fe ( II) to form Fe ( III ). In the absence of oxygen, the concentrations of CFe (III) and H 2 SO 4 in the acidic solution of ferric sulfate are respectively Related to arsenopyrite in accordance with section - the possibility of oxidation of a mechanism is very complex. Although this - mechanism is possible in principle, it does not cause doubt (at least in the initial stage of oxidation, because the concentration of Fe ( III ) ions in the solution is extremely low), but it is evaluated by direct experiment. this - in the whole mechanism of the oxidation process of the role is quite complex. This is because there is an oxidation product of pyrite and arsenopyrite- Fe (III) ions in the solution itself . Therefore, the following method is utilized, that is, under the action of oxygen (the temperature is These test results (FIG. 2.6) shows that, under the action of oxygen, arsenopyrite oxidation rate in the ferric sulfate solution in playing faster than in the absence of oxygen - more. So these  The test results show that the arsenic pyrite is oxidized according to the above two mechanisms. In industry, the processing conditions employed arsenic sulphide concentrates, each half and what percentage of these two mechanisms, it will depend on a particular implementation leaching autoclave leaching. However, in all cases it should be expected that when the Fe (III) concentration in the solution is relatively high, the relative specific gravity of the second mechanism will increase as the leaching process proceeds.
