Priority Lithium Extraction Process for Wet Recovery of Waste Lithium Iron Phosphate Batteries
This article provides a detailed introduction to a process flow for priority lithium extraction and wet recovery of lithium carbonate.Firstly,aluminum is removed with alkali,followed by acid leaching to separate iron phosphate.After impurities are removed,lithium is precipitated.The process flow is simplified,the reagent consumption is low,and the lithium leaching selectivity is high.The process economic benefits are relatively better.It can provide a process technology route for iron phosphate battery recovery enterprises with simplified process flow,low reagent consumption,high lithium leaching selectivity,and relatively better process economic benefits.
