摘要
以轧钢铁鳞为原料,经硫酸熟化、溶解得到硫酸铁溶液,研究了固液比、熟化过程、硫酸浓度等对铁溶出率的影响.实验结果表明,当固液比为1.2～2.5 g/mL(铁鳞/浓硫酸),硫酸浓度为98%,熟化温度20℃时熟化时间为20 h,熟化温度120℃时熟化时间为2 h时可获得高含量的铁溶液.
Ferric sulfate was obtained by H2SO4 maturating and dissolving using milling scale in steel plant as raw material. The influence of scale/H2SO4 ratio, maturation, H2SO4 concentration on iron stripping was intensively studied. The results show that a high-concentration solution of iron ion can be obtained at scale/H2SO4 ratio of 1.2- 2.5 （g/mL）,maturation time of 20 h when temperature is 20 ℃ or 2 h when maturation temperature is 120 ℃ and H2SO4 concentration of 98%.
