摘　　要：针对硼泥中的有价元素镁未得到充分利用,以工业硫酸和硼泥为原料制备出七水硫酸镁,为硫酸镁的生产开辟了一条新的途径,同时又治理了硼泥对环境的污染。讨论了酸浸温度、酸浸时间、液固比及硫酸浓度对镁浸出率的影响,确定了合理的工艺条件:酸浸温度100℃、酸浸时间2h、液固比为4:1、硫酸浓度50%,在此条件下镁的浸出率为95%。The technique of preparing epsomsalt from sulfuric acid and boron mud is developed to solve the problem of not fully - used magnesium left in the boron mud. It not only provides a new way of epsomsalt production, but improves the environmental pollution caused by boron mud. The article discusses the influences of the leaching temperature, the leaching time, the proportion of liquid to solid and the concentration of sulfuric acid on the pro- portion of leaching magnesium. And it also works out the reasonable technical condition as follows： the leaching temperature 100℃, the leaching time 2h, the proportion of liquid to solid 4：1, the concentration of sulfuric acid 50 % and the proportion of leaching magnesium is 95 % on this condition,
