Preparation of Lithium-ion Battery-Grade Cobalt Sulfate by Solvent Extraction AITranslate
Abstract AITranslate
Research is made on the process for preparation of lithium-ion battery-grade cobalt sulfate from crude cobalt hydroxide.And the process flowsheet is as follows：impurity removal by preferential dissolution with dilute sulfuric acid,reducing leaching,Fe,Mn and As removal by oxide precipitation,Ca and Mg removal by fluoride precipitation,deep purification and impurity removal by extraction with P204,Ni and Co separation and Na removal by extraction with P507.The electronic-grade cobalt sulfate suitable for producing lithium cobalt oxide has been obtained through the above process.
