| Abstract: | Iron and zinc was extracted from waste circuit board powder with sulfuric acid as reagent.The influence of sulfuric acid concentration,microwave power and microwave irradiation time on extraction effect was studied.The experimental results showed that:when 5 g metals,50ml sulfuric acid,concentration of sulfuric acid 3 mol/L,microwave power 793w,and microwave irradiation time 120 s,iron and zinc leaching rate reaches 74.4% and 93.2 %,which is satisfying. |
