Theory and Technology for Profound Reduction of Refractory Iron Ore
Description
This book systematically summarizes and condenses the groundbreaking work the author and their research team have done in recent years in the profound reduction of iron ore. In response to the challenges of utilizing certain iron ore resources in China that are difficult to process using conventional beneficiation methods, this book introduces the concept of profound reduction. By employing advanced detection technologies and methods such as software simulation, image analysis, and micro-area composition analysis, the book uncovers key scientific issues in the reduction process. These include the phase transformation, the measurement and control of iron particle size, the migration of phosphorus elements between phases, and the thermodynamic and kinetic mechanisms. It also details the development of a series of new profound reduction technologies and the establishment of a comprehensive theoretical and technical framework for the profound reduction of iron ore. This book is a valuable reference for university faculty and students, researchers, and engineering professionals engaged in fundamental and applied research in mineral processing engineering and metallurgical engineering.
