Mineralogy refers to the systematic study of all minerals, including their description, physical environment, crystallography and chemical characteristics. Applied mineralogy is focused on inorganic non-metal materials, and their sampling, analysis, synthesis, preparation, evaluation and property identification. Process mineralogy is a type of applied mineralogy that concentrates on solving issues related to ore processing. The goal of process mineralogy is to recognize, diagnose and forecast the mineralogically affected or regulated processing properties of an ore. They are also used as essential components of building materials like marble, plaster, granite, limestone, glass, cement and gravel. This book includes some of the vital pieces of work being conducted across the world, on various topics related to applied mineralogy. It will serve as a valuable source of reference for graduate and postgraduate students. Most of the topics introduced in this book cover new techniques and the applications of this field.
