Abstract
As a new method of nickel extractive metallurgy, the process of chlorine leaching-purification-electrolysis fornickel sulphide concentrate usually uses solvent extraction as its purification. After some running times the purification bysolvent extraction would destroy the characteristic of organic phase and influence the use of extractant. So the removal ofiron must be made independently at the beginning of purification. In hght of the composition of chlorine leaching solutionof nickel concentrate, iron removal by goethite process was studied. In chloride system the effects of many factors, suchas quantity of oxidizing agent, temperature of reaction, pH value, time of reaction, on iron removal were explored andoptimum condition of iron removal process was obtained. Tne results show that by this process efficient separation hasbeen made. Iron removal efficiency is over 99.8%, purified solution contains iron below 0.01 g/L, the loss of Ni, Co iniron residue less than 0.3% under the condition of oxidizing agent 5 g/L, pH = 2.5～3.0, at 85℃, for 2 hours.关键词
