Abstract
The extraction of zinc from zinc sulfate solution was investigated, using 20% saponified D2EHPA as an extractant and 260# sulfonate kerosene as a diluent. The solution was stirred for 8 min at phase ratio (V o/V a) of 1.0:1.0, initial pH of 2.0 and stirring speed of 200 r/min. The results show that 75% zinc can be extracted from the zinc sulfate solution when the concentration of zinc is 18.7 g/L after being settled for 10 min. 88.60% zinc can be stripped by 196 g/L sulfuric acid, and zinc ion can be separated from ferric ion.
