Abstract: A lithium-bearing porcelain stone deposit in Jiangxi Province is a newly proved superlarge deposit. In order to provide reference for the recovery and utilization of lithium and rubidium in the re⁃ sources，the process mineralogy study on petrology，mineral composition，dissemination characteristics and occurrence state of the representative ores is emphatically carried out. The results showed that the light-colored mica in the ores can be divided into native mica and nascent mica，and the embedded granu⁃ larity is mainly between 0.045 mm and 1 mm. Lithium mainly occurs in mica，and rubidium mainly occurs in mica and feldspar.

Key words: process mineralogy, occurrence state, dissemination characteristics, lithium-bearing por? celain stone
