摘要

•The mechanism of lepidolite-potash calcination process was studied.•The calcination could generate acid-soluble KAlSiO4 and water-soluble silicates.•Over 95% of soluble lithium and potassium could be easily extracted from generated silicates.•The solid residue KAlSiO4 could be easily recovered.
