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.
