Hydrometallurgy of Rare Earths: Extraction and Separation

Hydrometallurgy of Rare Earths: Extraction and Separation provides the basic knowledge for rare earth extraction and separation, including flow sheet selection criteria and related technology. The book includes the latest research findings on all rare earth separation processes, methods of controlling operation costs, and strategies that help lower wastewater and waste solid discharge. It discusses many real process parameters and actual situations in rare earth separation plants, also examining the basic principles, technologies, process parameters and advances and achievements in the area of rare earth extraction and separation.

In addition, the book covers extraction separation theory as developed by Professor Guanxian Xu and Professor Chunhua Yan and the creative use of a computational simulation program to replace the bench scale and pilot plant tests and directly design rare earth extraction separation processes.

Outlines the theory of solvent extraction and separation of rare earths (REs)Provides the necessary tools for a REs separation plant designIncludes a unique simulation program for the calculation of all process parametersIncludes Chinese nomenclature that is useful for identifying the various processes, also comparing it to the global literature
