Wills' Mineral Processing Technology Very good book for a student, or as a reference for professional with a non metallurgical background. Unfortunately the book does not contain and details of gold metallurgy (Cip. Cil. MC etc), although this huge area is covered in other books it would be useful to have a chapter with the basics in this book

12%Synopsis. A number of modern techniques suitable for the design of crushing and grinding circuits are described. The methods are based on extensive use of mathematical models of crushers, mills and classifiers and are seen as alternatives to conventional comminution design methods based on Work Indexcalculations.
