Technological Research on Cobalt Leaching from Iron Ore Tailings in Citric Acid-Ammonium Bifluoride System AITranslate
Abstract AITranslate
Technical conditions were studied for cobalt leaching from iron ore tailings in citric acid-ammoni- um bifluoride system. The results of orthogonal experiments show that reaction temperature is the primary influencing factor of cobalt leaching rate, reaction time and ammonium bifluoride concentration are second- ary,and citric acid concentration is the last one. The more reaction time and ammonium bifluoride concen- tration, the higher cobalt leaching rate. The results of the further experiment to determine the optimal con- ditions show that cobalt leaching rate can reach 90.61% with 100 ℃ reaction temperature, 20 g/L citric acid concentration,40 g/L ammonium bifluoride concentration and 4.0 h reaction time.
