Features: This book includes the main innovative achievements obtained by the authors through years of fundamental research and production practice on weathering crust leaching rare earth deposits, supported by the National Natural Science Foundation of China, the National Outstanding Young Scientists Foundation of China, the Jiangxi Natural Science Foundation, and national key research projects on rare earth. The book is divided into two parts, consisting of 12 chapters. The first part primarily discusses the formation of weathering crust leaching rare earth deposits, the properties of rare earth ores, the occurrence state of rare earth in ores, the relationship between rare earth and clay minerals, the migration, enrichment, fractionation, and variation patterns of rare earth distribution in weathering crusts. The second part focuses on the theoretical foundations and production practices of three generations of rare earth extraction processes from weathering crust leaching rare earth deposits, as well as the quality control of products from weathering crust leaching rare earth deposits and the development of green extraction processes. This book is available for engineering technicians engaged in rare earth production, design, research, and management, as well as teachers and students in relevant disciplines at universities and colleges for reference.
