中文摘要: 针对电炉弧烟尘处理利用，进行了电弧炉烟尘球团焙烧一洗涤脱制备低卤含量氧化锌的试验研究，取得了满意的结果，在最佳球团焙烧工艺条件下，锌的挥发率〉94％、铅的挥发率〉90％，氟主要以难挥发的MnF2形式留在窑渣中，挥发氧化锌烟尘中难溶氟化物含量少，洗涤脱卤效果明显，洗涤后含锌62．14％，氟0．011％、氯0．20％，基本满足株冶氧化锌系统浸出原料的要求。
Abstract:The experiments of producing zinc oxide with low halogens content by pellet roasting-washing process from electric arc furnace(EAF) dust was carried out,and under the optimum experiment condition,the volatilization rate of Zn and Pb is over 94%,90% respectively;and majority of fluoride is fixing in the residual pellets as MnF_2,the crude zinc oxide dust has little fluoride,which can be de-fluoridated by soda washing easily,and the last product(62.14% Zn,0.011% F,0.20% Cl),met the demands of leaching material of zinc oxide treatment system in Zhuzhou Smelter Group.
