| Abstract: |
| The mineral phase of arsenic in antimony oxide powder is investigated, according to the property of As_2O_3,the arsenic is transformed to sodium arsenate using the following process: roasting with sodium carbonate in high temperature,de-arsenic with carbonic acid,vacuum filtering and water-washing.The factors that influenced leaching rate of arsenic are discussed.The leaching rate of arsenic is above 94% on the optimized condition. |
