We are planning to publish a book on Alumina Technology covering various technical aspects with emphasis on process & design of Metallurgical and Non-Metalurgical (Speciality grades) Alumina Plants including Byproducts. We have structured a Draft Table of Content for the purpose. If everything goes well, this book will be published by early 2014 by a Publisher of International repute.
In our opinion, the proposed new book will be unique with regard to availability of in depth technical data / information generally required by process engineers and plant designers as no such book is available in the market particularly on Bauxite, Hydrates and Aluminas.
Given below, please find the draft table of content seeking your views for addition / deletion / modifications, you feel appropriate, for enrichment.

I was waiting for such a book. Congratulations, Sir.If If the book can be in volumes, it will be much more useful and other volumes on Plant upkeep may also be thought of.
ReplyDeleteDear Mr. Siddiq,
ReplyDeleteThanks for your valued advice. We have thought of publishing the book precisely in single volume covering, process, design, engineering & execution of Metallurgical and Non-metallurgical grades of hydrates and aluminas.The book will involve many technical issues which are not available in any published literature so far.
Lot of efforts have already gone in and many chapters are already under scrutiny and review.
We welcome your suggestion as house keeping and safety are prime concern in any mineral processing plant and more so in Alumina refinery.
Thanks.

When this book on alumina refinery will be published and released
ReplyDeleteDear Sir,
ReplyDeleteWhen can we expect this book in the market ?
Warm Regards,
Ravi Kumar.
Dear Mr. Ravi Kumar,
ReplyDeleteGenerally I adhere to schedule committed to my organization and my friends as well. But on publication of the book of Alumina technology, there will be little delay because of my deep involvement and pressing needs in execution and commissioning of a prestigious project in India itself. Though majority of manuscript have already been completed but I wish to include many many critical technical issues to be covered in this book in the benefit of friends of Alumina fraternity. Please bear with us for some more time. The basic purpose for publication of this book not to make money but to bring many hidden technical aspects on the surface by clarity in expression which is not available so far in any published literature across the globe.
Thanks and regards.
Kunwar Rajendra
