摘　　要：富硼渣与焙烧后的硼镁矿的化学组成相似,可代替硼镁矿作为硼和镁的来源。以富硼渣为原料,采用硫酸一步法分解制取硼酸和一水硫酸镁,以及用碳碱法制取硼砂均得到了较佳结果,硼酸的回收率达到71.86%,一水硫酸镁的回收率为55.77%,硼砂的回收率达到71.93%。硼酸、一水硫酸镁和硼砂纯度均很高,符合国家质量标准。比较两种方法,综合环保与市场因素,采用硫酸分解一步法生产硼酸更为合适。The boron-rich slag is similar to ascharite in the chemical composition, which can replace the ascnante as the source of boron and magnesium. The sulfuric acid one-step method was determined for ti^e preparation of boric acid and magnesium,and the carbonate-alkaline method for borax. The both results are very good. The recovery of boric acid, magnesium sulfate monohydrate and borax is 71.86% ,55.77% and 71.93% respectively,which fits na- tional quality standards because of their high purity. Compared to the two methods and taking into account environ- mental and market factors,the production of boric acid and magnesium sulfate monohydrate using sulfuric acid one- step method is more appropriate.
