Abstract
The conditions of the selective and joint extraction of copper and ferrum impurities from a nickel electrolyte by extraction using a mixture of oleic acid and trietanolamine in kerosene were determined: extraction Fe (III) at 3 < рН ≤ 4, 1 ≤ В:О ≤ 4 and t = 40 °C; extraction Cu (II) at 5 ≤ рН ≤ 6, 1 < В:О ≤ 4 and t = 40 °C; joint extraction of copper and ferrum at рН = 5-6, 1 ≤ В:О ≤ 4 and t = 40 °C. The process flow sheet of selective extraction of ferrum and copper from a nickel electrolyte by extraction using a mixture of oleic acid and triethanolamine in kerosene is given.
