| 摘 要： | 通过对锑氧粉中砷物相的分析,根据三氧化二砷的性质,采用碳酸钠高温焙烧—碳酸化除砷—真空过滤—水洗—真空过滤工艺,将锑氧粉中的元素砷转变为砷酸钠浸出,对影响浸出的几个因素进行了研究,择取优化条件,砷的浸出率可达到94%左右。

| 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. |
