摘要:
采用传统火法冶炼设备反射炉回收高砷高硫难处理金精矿副产品三氧化二砷时，存在热效率较低，机械化、自动化程度不高等缺点。为降低生产能耗、提高自动化水平及经济效益，中南黄金冶炼公司在钢带炉的基础上，通过优化改进，形成了一项全自动带式电炉三氧化二砷蒸馏提纯技术。生产实践表明：金精矿冶炼副产品三氧化二砷纯度从96.5 %提高至99.0 %，堆密度从0.8 t/m3提高至1.8 t/m3；该技术安全环保，设备性能良好，机械化、自动化程度高，能耗低，应用前景广阔。

Abstract:
When arsenic trioxide,the byproduct of high arsenic high sulfur refractory gold concentrates,is recovered in reverberatory furnace,a conventional fire assay smelting equipment,the heat efficiency is poor,and the mechanization and automation level are low.In order to reduce energy consumption and improve automation level as well as economic benefits,Central South Gold Smelting Company optimized and renovated into a technique that distills and purifies arsenic trioxide with fully automatic belt furnace.The production practice shows that the purity of arsenic tri-oxide,the byproduct of gold concentrates smelting,is increased from 96.5 % to 99.0 %,the bulk density is increased from 0.8 t/m3 to 1.8 t/m3;the technique is safe and environment-friendly,the equipment performance is good,the mechanization and automation level is high,and the energy consumption is low,and the application prospects are good.
