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 ores, supported by the National Natural Science Foundation of China, the National Outstanding Young Scientists Foundation, the Jiangxi Natural Science Foundation, and national key research projects on rare earths. The book is divided into two parts, comprising 12 chapters. The first part primarily discusses the formation of weathering crust leaching rare earth ores, the properties of rare earth ores, the occurrence state of rare earths in ores, the relationship between rare earths and clay minerals, the migration, enrichment, fractionation, and variation patterns of rare earth partitioning 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 ores, as well as the quality control of products from weathering crust leaching rare earth ores and the development of green extraction processes. This book is suitable for engineering technicians engaged in rare earth production, design, research, and management, as well as faculty and students in relevant disciplines at universities and colleges.
