| 摘 要： | 采用20％N235＋30％仲辛醇＋50％煤油（均为体积百分比）萃取体系，在相比O／A=2：1和单级萃取的条件下，处理含铁（13．47）的赤泥浸出液，振荡混合时间15min，铁的萃取率达到99．62％．然后用0．1mol／L的稀盐酸反萃有机相提取铁，在相比O／A=2：1的条件下，经单级反萃，反萃后液含铁10．18g／L，铁的反萃率为75％．采用石灰中乖，渣中含铁达56％．

| Abstract: | With 20% N235 ＋ 30%SINoctanol ＋ 50% kerosene （in v/v）, the leaching fluid solution with Fe^3＋ concentration of 13.47 g· L^-1 is treated. Under the conditions of O / A =2 and one-step extraction, the oscillation time is 15 min, and the extraction rate of Fe^3＋ is 99.62%.Then under the condition of O/A=2：1, stripped with 0.1 mol/L HCl ,the fluid of stripping includes 10.18 g·L^-1 iron and 0.10mol ·L^-1 HCl.About 75% Fe^3＋ of N235 Organic is stripped. After tha neutralization with lime, the cinder contains 56% iron. |
