摘要:
采用传统法对贵州回龙矿石进行试验，测得矿石中硫磺、硫酸盐及硫化物的质量分数分别为0.42%、0.13%、3.10%，而采用MLA仪器该矿石进行分析，结果显示矿石中硫化物占95%，几乎没有硫磺.这表明传统的硫赋存状态分析方法无法准确测定该矿石中的硫磺、硫化物的含量.针对传统检测方法对硫磺、硫化物的分析误差较大的问题，提出了先用四氯乙烯来萃取矿石中的硫磺，然后用碳酸钠溶液浸出硫酸盐，最后分两步浸出硫化物的分相流程的新方法.改进的新方法测得矿石中硫磺、硫酸盐及硫化物的质量分数分别为0.04%、0.13%、3.48%，该结果跟仪器测试结果非常吻合，表明该新方法准确度高，也适用于含有重晶石的矿石中硫赋存状态的分析.
Abstract:
The traditional sulfur chemical phaseanalysis (TSCP) was carried out in GuiZhou HuiLong ore. The results show that contents of sulfur, sulfate and sulfide are 0.42%, 0.13%, 3.10%, respectively. 95% of sulfide was determined by mineral liberation analyzer with almost no sulfur. It means that accurate contents of sulfur and sulfide cannot be obtained with the method of TSCP. Due to larger error of TSCP method, a new method was proposed. First, sulfur was extracted by chloroethylene, then sulfate was leached with sodium carbonate solution, last sulfide was leached by two steps from ore. The new method was applied to experiments of Guizhou HuiLong ores, the results are as follow: Contents of sulfur, sulfate and sulfide are 0.04%, 0.13%, 3.48%, respectively, which are very consistent with results of mineral liberation analyzer. The new method has more accurate result and can be applied to analyzing the ore containing barite.
