摘要
采用火法工艺对铜闪速炉烟灰中的砷进行脱除,通过正交试验考察了焦炭配入量、温度和焙烧时间对脱砷的影响,得到最佳的脱砷条件:焦碳配入量12%,焙烧温度1 100℃,焙烧时间1 h,在该条件下脱砷率超过80%,铜回收率大于95%。
The de-arsenic from the dust of copper flash smelting furnace applying the pyrometallurgical method is studied. The effect of temperature, roasting time and coke additive on de-arsenic is investigated using the orthogonal experiment. The results indicate that de-arsenic rate is above 80 % and the recovery of copper is above 95% under the conditions of 1 100℃ roasting temperature, 1 h roasting time and 12% coke additive.
