Highlights

  • Like the present review, this book, dealing with magnetic methods for the treatment of minerals, is a little late in arrival

  • When a monumental text such as this (692 pages) arrives on the shelves, the younger engineer, the graduate researcher, has a genuinely authoritative text he can turn to. This is the kind of book on magnetic separation we would all have liked to have written but did not have the energy and industry to write

  • The text comprises 6 chapters, the first of which contains a useful summary of the magnetic properties of many of the more important naturally-occurring minerals
