中文摘要: 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.
