| 摘 要： | 采用富氧顶吹装置模拟辉锑矿挥发熔池熔炼的行为,考察了氧气系数、初始渣Fe/SiO_2、CaO含量对熔炼渣中锑含量的影响。在氧气系数为1.04、初始渣Fe/SiO_2=0.94、CaO 15%的最优条件下,熔炼后渣含锑为1.8%。采用SEM-EDS对渣中锑的物相及分布行为进行了表征,发现熔渣中锑以微小的金属粒子形式存在。通过加入一定量的锑锍作为捕集剂,并在高温下对锑渣进行贫化,使渣中的锑含量由沉降前的2.36%降低至0.86%。辉锑矿可以采用富氧挥发熔池熔炼—熔炼渣高温贫化工艺进行处理。

| Abstract: | Volatilization behavior of stibnite was simulated by an experimental equipment of oxygen enrichment top blowing. Effects of oxygen factor, Fe/SiO2 and CaO content in initial slag on Sb content in smelting slag were studied. The results show that Sb content in smelting slag is 1.8% under the optimum conditions of oxygen factor of 1.04, Fe/SiO2=0.94, and CaO of 15%. Phase and distribution of Sb in slag were analyzed with SEM-EDS. Sb exists as micro elemental particles in the slag. Sb content in slag reduces from 2.36% to 0.86% after depletion at high temperature by adding some antimony matte as collecting agent. Stibnite can be treated by the process of oxygen enrichment bath smelting and high-temperature depletion. |
