Extraction and Recovery of Cobalt from the Heap Leaching Solution of Copper-Cobalt Ore with HBL110 AITranslate
Abstract AITranslate
A new process was applied of copper extraction with Mextral 984 Hat first and then cobalt extraction with a new extractant of HBL110,to recover cobalt from the heap leaching solution of copper-cobalt ore containing such impurities as iron.The effects were investigated of extractant concentration and saponification rate,equilibrium pH value,temperature and phase ratio on cobalt extraction.The experimental results show that cobalt extraction rate is over 95% after four-stage countercurrent extraction under the conditions as follows：extractant concentration of 50.5%,saponification rate of 50%,equilibrium pH value of 2.4~2.6,phase ratio of 1∶1,temperature of 30 ℃ and time of 5 min.The loaded organic phase was washed by pure water and then cobalt was stripped.The stripping rate of cobalt is more than 94% after four-stage countercurrent stripping with 0.7mol/L H2SO4 solution under the conditions as follows：phase ratio of 8∶1,temperature of 40℃and time of 5min.Cobalt is enriched and separated from such impurities as iron,manganese and magnesium,and its concentration is 20g/L in the stripped solution.
