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。
The mineral phase of arsenic in antimony oxide powder is investigated, according to the property of As2O3, 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.
