摘要
设计了一种适用于锑氧粉熔池还原熔炼的低熔点渣SiO_2:FeO:CaO:Na_2O=30:34:12:24,通过单因素试验法研究熔炼时间、焦率和熔炼温度对锑氧粉还原熔炼过程的影响。得到的最佳条件为:熔炼时间50 min、焦率12.5%、熔炼温度1 000℃,在此最优条件下进行扩大试验,金属锑直收率为92.66%,渣含锑为1.06%,粗锑品位为97.09%,均优于传统反射炉工艺。
A low melting point slag system of SiO2 ： FeO ： CaO ： Na2O=30 ： 34 ： 12 ： 24 was selected to investigate effect of smelting time, coke rate, and smelting temperature on reduction smelting of antimony oxide in bath smelting. Average direct recovery rate of metallic antimony is 92.66% with antimony grade of 97.09%, and average mass fraction of antimony in slag is 1.06% under the optimum conditions including smelting time of 50 min, coke rate of 12.5%, and smelting temperature of 1 000℃. Those indexes are all superior to those of traditional reverberatory process.
