Reaction Steps
The zinc chloride solution is then subjected to a cationic extractant (Di-2-ethylhexyl phosphoric acid) D2EHPA (50%) and 50% kerosene to produce a loaded solvent containing about 5 gpl zinc. An O/A ratio of about one is employed to produce a raffinate containing less than 0.05 gpl zinc. The loaded organic is contacted with a 200 gpl HNO3 strip solution with O/A ratio of 1/4 to produce a zinc nitrate solution containing 30 gpl zinc and about 150 gpl HNO.
