Mineral processing / Обогащение полезных ископаемых

This book is designed to describe the basic principles used in the concentration of specific minerals from their ores. It further deals with the development of these principles in industry and the requirements for effective process control. The earlier editions were written in connexion with the teaching of mineral technology at the Royal School of Mines in London, and were designed to be used together with the laboratory study and plant experience essential for a sound grasp of this science and its applications. This correlation of principles and practice is continued here.
Physical science is operative in the whole field of human activity. In the study of mineral dressing, which calls for special application of the laws of physics, chemistry, and electricity, the term "physical science" is here used to embrace these three categories. Its technology derives from fundamental physical laws, and operates at two levels-basic and applied. The word "technology" is here used in its sense of the combination of technical skill and economic justification, since successful field operation is mainly judged by financial criteria. "Basic technology" considers the general principles applicable to a standard type of operation, while "applied technology" connotes specially imposed variations designed to improve the treatment of one specific ore body <...>
