Foreword

Dr. C. K. Gupta is a very distinguished colleague of mine. I have been familiar with his pro-

fessional career over a long period. A very large number of research papers, reviews, and

several books authored by him bear ample testimony to the diverse and wide-ranging con-

tributions he has made to date to the field of chemical metallurgy. I was indeed very happy

to accept the invitation from him to write a foreword for the present volume entitled, “Chemi-

cal Metallurgy – Principles and Practice”, being published by Wiley-VCH Verlag, Germany.

This volume provides in one place a self-contained and adequately detailed coverage of

the chemical metallurgy of the major metals, common as well as less common. It has been

brought into being as an exceedingly well-structured treatise. The presentation has been

organised in seven chapters. The first chapter gives a general appraisal of the whole field of

chemical metallurgy. The coverage also includes a brief account of resources. The next two

chapters are devoted to thermodynamics and kinetics and to processing of minerals. The

remaining three chapters deal, respectively, with pyrometallurgy, hydrometallurgy, and

electrometallurgy. The last chapter attends to energy and environmental considerations.

Physicochemical principles provided for the various unit operations and description of the

key details of the processes deserve special mention as being among the attractive features

of this volume. One must also additionally note the emphasis laid on the less common

metals in the presentation. This is decidedly an additional special feature of the book. Chemi-

cal metallurgy of the less common metals described with pertinent principles involved has

not been done earlier in one place as has been accomplished in this publication. The abun-

dance of illustrations and the comprehensive collection of carefully selected references ap-

pended to each chapter add to the value and enhance considerably the overall strength of

the book. On the whole, the presentation displays an imaginative and competent handling

of the subject matter and really reaches out to the readers.

The volume deals with a very wide technical field and will be of interest and relevance to

many disciplines, particularly metallurgy, chemical engineering, and chemistry. It will un-

doubtedly be a valuable addition to the list of available books dealing with chemical metal-

lurgy. At the same time, this volume will be very useful to professionals working in the area

of extractive and process metallurgy. The present book has had the benefit of Dr. Gupta’s

wide and long-standing experience in the field in full measure and will certainly be greatly

valued by those to whom it is addressed. I wish this publication all success and hope it will

be as useful as the other books which Dr. Gupta has authored.

Preface

As the title, “Chemical Metallurgy: Principles and Practice” implies, this text blends theory

with practice covering, of course, a good deal of descriptive items on hows and whys of

extraction and processing of metals and materials. While the processes for the extraction of

the common metals have been provided in sufficient detail, I have tried to go in equal

depth, if not more, to provide focus on the less common metals. I have, however, avoided

lengthy descriptions of current commercial practices as these change rapidly. Rather,

selected examples have been presented to illustrate the various principles dealt with in the

text. It is expected the readers will supplement this text with appropriate examples of cur-

rent practices. All along I have made an effort to lead the treatment to a point where the

readers will find the transition to more advanced and specialized metallurgical engineering

textbooks, texts, and monographs with emphasis on chemical metallurgy quite easy.

This book altogether contains seven chapters. In Chapter 1, I have endeavored to organ-

ize the text with a view to acquainting the readers with a miscellany of relevant information

and preparing them for going into the contents of the subsequent chapters. Chapter 2 deals

with mineral processing, which usually takes the position as the principal front-end opera-

tion in the overall process flowsheet for metal extraction. Chapter 3 pertains to thermo-

dynamics and kinetics which provide unequivocally a sound basis for the understanding of

the processes. The next three chapters delve into pyro-, hydro-, and electro-metallurgy, in

that order. Chapter 7 addresses certain representative issues concerning energy consump-

tion and environmental pollution aspects especially pertinent to chemical metallurgy

operations.

It is difficult for an author to praise the virtues of his own book. However, just to say a few

words, I may add that, as pointed out, I have systematized the organization of the text in the

chapters by presenting the process principles first and then following up with process prac-

tice. I have in my opinion adopted a lucid style – readable, interesting, intelligible, and

informative – for a wide and varied audience. It has on the whole been a delightful experi-

ence for me to produce and place this book for the readership it will fetch. May I end by

saying that I earnestly believe the book will provide an interesting reading and knowledge,

and will certainly be highly successful in putting the readers into the fascinating world

of preparative metallurgy, into the arduous journeys through which different metals and

materials traverse to come into their useful beings and finally make themselves available in

the service of man. A carefully selected reference list and a good number of clear illustra-

tions may be treated as additional features which should not be lost sight of. All these

presentations have not been carried out without incorporating the backing of the principles

involved and this very element should go to provide additional attractions and spice, so to

say, for the book.
