摘要
通过炼铜烟囱灰的焙烧脱砷实验,研究了粒径、温度以及双氧水等对脱砷效果的影响,结果表明:未经过筛选的烟渣焙烧后砷含量最低,即砷的去除率最高;铜烟囱灰焙烧去砷的最佳温度为700℃,焙烧时间2h,砷去除率可达82.75%。
Through the experiment of arsenic removal by roasting copper chimney ash,the effects of particle size,temperature and hydrogen peroxide on arsenic removal were studied.The best temperature of arsenic removal by roasting copper chimney ash is 700℃,the roasting time is 2 hours,and the arsenic removal rate can reach 82.75%.
