, helps further understanding of the various methods commonly used in mineral beneficiation and concentration processes. Application of theory to practice is explained at each stage, helping operators understand associated implications in each unit process. Covers the theory and formulae for unit capacities and power requirements to help the designer develop the necessary equipment and flow-sheets to economically attain maximum yield and grade.This second edition describes theories and practices of design and operation of apparatus and equipment, including an additional chapter on magnetic, electrostatic, and conductivity modes of mineral separation. Basics of process controls for efficient and economic modes of separation are introduced.
- Outlines the theory and practice in the design of flow sheets and operation of an integrated mineral processing plant
- Introduces the basic magnetism, electrostatic, conductivity, and dielectrophoresis properties of minerals and related separation techniques
- Describes automation in mineral processing plants allowing maximum yields and consistent high concentrate grades
- Outlines problems and offers solutions in the form of various examples
Metallurgists and process engineers as well as university students as an introductory guide to large scale industrial operations to liberate and recover commercially minerals from ores. Students and engineers interested in the disciplines of metallurgy, chemical engineering, mechanical and electrical engineering (including electronic engineering), both in operation and research are expected to benefit
