| Abstract: |
| With virtue of mild operation condition, faster oxidation velocity, lower invest cost and less pollution, refractory gold ore pre-oxidation by chemical reagent is a technique of good prospect. Nitric acid pre-oxidation, alkaline pre-oxidation, electrochemical intensive electrode and their industrial application are introduced respectively in the paper. |
