Process Optimization of Recycling Lithium from Waste Ternary Power Battery AITranslate
Abstract AITranslate
In view of the long recovery process and low lithium recovery rate of waste ternary power batte-ry,and the situation that most enterprises only produce crude lithium carbonate and lithium phosphate,and the added value of products is low,the lithium extraction process of flotation-reduction roasting carbonization is used to produce battery grade lithius carbonate.The results show that under the optimized process index and device sign parameters,the recovery rate of lithium is more than 90%.The removal of most ne-gative graphite by flotation can effectively reduce the specifications of leaching equipment and pressure filtration equipment,shorten the subsequent recovery process of nickel,cobalt and manganese,and reduce the acid and alkali consumption in the extraction process.The impurity content of the solution after lithium extraction by carbonization is low,and the battery grade lithium carbonate can be produced after purification,which can improve the economic benefit of the enterprise.
