Study on the Preparation of Battery Grade Iron Phosphate by Coprecipitation Method of Phosphorus Iron Slag
This study uses phosphorus iron slag as raw material and adopts a three-stage process of dissolution,co precipitation,and calcination to prepare battery grade iron phosphate.The optimal process parameters for co precipitation are studied.The results showed that during the reaction,the molar ratio of iron to phosphorus in the solution was 1:1.0,the reaction pH was 1.0,the reaction temperature was 80℃,the reaction time was 5 hours,and the prepared iron phosphate iron to phosphorus molar ratio was 0.97.After high-temperature calcination,qualified battery grade iron phosphate could be obtained.
