【摘要】：某高爐瓦斯灰粒度較細(xì)、成分較復(fù)雜,主要成分有氧化鈣、赤鐵礦、方解石、氧化鋅、炭等,鐵、鋅、碳含量分別為27.44%、8.76%、13.51%,主要含鋅礦物為氧化鋅,含鐵礦物為赤鐵礦,碳主要以焦炭的形式存在。為確定硫酸浸取鋅的合適硫酸濃度、液固比和浸出時(shí)間,進(jìn)行了3因素3水平正交試驗(yàn)。結(jié)果表明,硫酸濃度對鋅浸出率影響最顯著,其次是液固比;在硫酸濃度為0.6 mo L/L、液固比為7 m L/g、浸出時(shí)間為25 min情況下硫酸浸鋅,鋅浸出率達(dá)97.03%。
[Abstract]:The gas ash of a blast furnace is of fine granularity and complex composition. The main components are calcium oxide, hematite, calcite, zinc oxide, carbon, iron, zinc, carbon and so on. The contents of iron, zinc and carbon are 27.44 and 8.76 respectively. The main zinc bearing minerals are zinc oxide and the iron bearing minerals are hematite. Carbon mainly exists in the form of coke. In order to determine the appropriate sulfuric acid concentration, liquid-solid ratio and leaching time, three factors and three levels of orthogonal experiments were carried out. The results showed that the concentration of sulfuric acid had the most significant effect on the leaching rate of zinc. The next is liquid-solid ratio, the zinc leaching rate is 97.03 when the sulfuric acid concentration is 0.6 mol / L, the liquid-solid ratio is 7 mL / g, the leaching time is 25 min, and the zinc leaching rate is 97.03 when the sulfuric acid concentration is 0.6 mol / L, the leaching time is 25 min.
