The title Chemical Metallurgy may still
sound a little strange to materials scientists and engineers, but as a counterpart
to the more familiar “physical metallurgy” the name is entirely logical. In
fact, this book is concerned with all the
chemical, physicochemical, and chemical-physical aspects and problems of the
production of metallic materials in the
widest sense, and spans the range from
the scientific fundamentals to the technology of real processes. Therefore, this
unusually interdisciplinary book is concerned with the entire body of knowledge in this field. Most of the literature
in this area consists of individual works
that are confined to a single discipline,
and either deal with the theoretical
fundamentals (especially textbooks of
physical chemistry or its subdisciplines)
or concentrate on describing the different types of processes. Thus, the present
work is also of interest to the nonspecialist who wishes to get a broad view
of the subject or to begin work in the
field.
The considerable wealth of knowledge contained in the book is arranged
in such a way that the fundamentals and
the applications are treated together,
and thus the sequence of the chapters
switches between presenting the necesAngew. Chem. Int. Ed. 2004, 43, 659 – 662
sary physical and physicochemical basic
knowledge and discussing actual processes, following the path from the
starting material to the metal. Accordingly, Chapter 1, “Acquaintance”, presents the basic fundamentals in a consistent way. The characteristics of the
different metals are described, including
their crystallography, and their mechanical properties are discussed in the
context of engineering applications.
The available ore resources are briefly
surveyed, the properties of the minerals
are described, methods of extraction are
discussed, and different processing procedures are considered.
Chapter 2, “Mineral Processing”,
deals with the fundamentals and the
various processing methods. A discussion of methods for the quantitative
characterization of particles is followed
by detailed descriptions of comminution, milling, separation, and classification, including the various techniques
and the machinery. In Chapter 3, “Thermodynamics and Kinetics”, the author
explains in detail the physical and physicochemical laws upon which the metallurgical processes discussed in the following chapters are based.
The subjects of Chapters 4–6, which
treat the different types of metallurgical
processes in detail, are “Pyrometallurgy”, “Hydrometallurgy”, and “Electrometallurgy”. Each chapter begins
with the scientific fundamentals, then
describes the relevant processes and the
specific features of the metals under
discussion, including the technical
details of the reactors. For each type of
process the reactions are described
quantitatively and illustrated by examples, including information about the
effectiveness of different methods.
Lastly, Chapter 7, “Energy and Environment”, deals with the global aspects of
the extraction and use of metals, including data on the masses and energies
involved. The environmental burdens
associated with the various processes
are considered, and implications for
choosing between processing methods
are discussed.
The various processes and their
problems are described with a degree
of detail that befits their importance,
and cover the present state of the art and
the latest knowledge. As a consequence
of the way in which the subject matter is

arranged, one finds that different
aspects of a given process or problem
are treated in different chapters. There
are no cross-references in the text, and
therefore the reader needs to make use
of the comprehensive index to extract
all the information about a given problem. The information and discussions
are illustrated by many clear and easily
understandable diagrams and schemes,
although in some cases their unprofessional quality and lack of sharpness is
annoying. The introduction to the properties of the different metals at the
beginning of the book could have been
improved by including a chart of the
Periodic System, especially as it is referred to in the text. References for further
reading are given only at the end of each
chapter, where one finds a few important literature references relating to the
various problems discussed in the chapter—listed alphabetically according to
the authors' initials! No sources are
cited for the factual information and
data given, and therefore the reader
who wishes to refer to these must do
some laborious searching. Unfortunately the tables and formulas have not
escaped the inevitable printing errors,
which is more serious than just a minor
annoyance.
Despite these small criticisms, which
can perhaps be remedied in time for the
next edition, this book is emphatically
recommended for everyone interested
in the field, both those within and those
outside the area of “chemical metallurgy” (i.e., in the wider field of the
metal-processing industry), as an introductory handbook and reference source.
I hope that the work will reach a wide
readership.
