Abstract: Huichang County of Jiangxi Province hosts a number of kaolin ore deposits, but poor mining and processing methods have long resulted in huge waste of mineral resources and low effectiveness of the mines. Based on the previous work and geological characteristics of the mining area, sampling, processing and mining technique, this study has concluded that the kaolin in this area belongs to weathering sand-type ore. The main mineralization contains aplitization, granitification and pegmatization. The high-quality ores, resources amount, and exploitable value will provide some reference for further resource investigation and evaluation.
