Textbook of Hydrometallurgy, 2nd Edition F. Habashi Metallurie Extractive Quebec, 800 Alain apt 504, Sainte-Foy, Quebec, Canada GIX 4E7, 1999 ISBN-2-980-3247-7-9, 750 pages fully illustrated. I am sorry to tell you that C.V. Phillips did not review my book Textbook of Hydrometallurgy (2nd. edition) properly. He was surprised towards the end of his review that "little mention is made of the now important Sherritt pressure zinc process". Apparently, he overlooked pages 306 to 308 where the process is fully described, a flowsheet (Fig. 12.9) and a photograph of the plant (Fig. 12.10) are given. The reviewer also criticizes the absence of "wider updating of the bibliography -- -- --". It seems again that he did not see pages 19 to 29 and 717 to 720 which contain over 250 review articles, proceedings volumes, and books directly related to the subject. In fact because this is an important feature of the book it is mentioned on the back cover. What puzzles me further, is that Mr. Phillips still insists that fused salt electrolysis belongs to hydrometallurgy. By definitions hydrometallurgy is the metallurgy using aqueous solutions - - in fused salts, even traces water must be absent. I wish he takes some time to look up my volume 4 of Principles of Extractive Metallurgy devoted to Electrometallurgy and see how elecrowinning, electrorefining, and fused salts are discussed in relation to hydro- and pyrometallurgy. Finally, bacteria-assisted hydrometallurgy is fairly well treated in a special chapter (Chapter 8) and his criticism in this point is also unacceptable. Fathi Habashi, Professor of Extractive Metallurgy,Department of Mining, Metallurgical, and Materials Engineering , Laval University, Quebec City, Canada G1K 7P4 Re: Fathi Habashi's response to my book review of his text Hydrometallurgy 2nd Edition 1999. I would respond as follows to the points raised: i) 'Little mention of the Sherritt Pressure Zinc process'; I had noted pages 306-308 where reference is made to the process, via some text, the Figures 12.10 and 12.9. The process is such an important development that it deserves more coverage in light of the papers published on the process by E. Ozberk et al and the J. of Metals paper by Collins et al Volume 46 No 4 April,1994. ii) 'Wider up dating of the bibliography' - I have rechecked pp 717-720 and, with respect, I did not find a single acknowledgement to an article dated in the 1990's. In respect of pages 20-29 perhaps it's a pity that the journal Minerals Engineering does not appear often as it publishes many hydrometallurgy papers. I still feel that the 'Selected References' section could have contained far more post 1993 publications as there have been a vast number and a large number of Hydrometallurgy conferences around the world in the 1990's. iii) My comment on electrolysis processes was related to 'rounding off' of processes for metals involving hydrometallurgy, to assist students. I do not wish to enter further discussion on the point he raised, it was electrolytic finishes in general that I wished to address. iv) 'Biohydrometallurgy (chapter 8)' I had noted the 4½ page chapter on this subject but feel that the industrial importance of the topic deserves more detail in respect of the minerals now subject to bio-oxidation and bioleaching on significant industrial tonnage scale. I would have no further comments to add to the matter. Dr. C.V. Phillips, Camborne School of Mines, Redruth, Cornwall, UK. September 12th, 2000
