Book Description
Actuellement, prêt de 20%% de la production mondiale de cobalt, soient prêt de 10 000 tonnes et 60%% de la production mondiale de super-alliages à base de cobalt sont récupérés par les USA qui considèrent ce métal comme hautement stratégique au point que sa carence pourrait affecter sérieusement ses domaines économiques, industriels et militaires ainsi que ceux de nombreux pays hautement industrialisés. On trouve ainsi dans cet ouvrage des informations sur l'origine, l'élaboration du cobalt, son recyclage et son utilisation tout cela illustré de près de 80 flow-sheets, croquis et graphes. Cet ouvrage est un recueil, une mine d'informations, d'expériences et de pratiques industrielles utiles à avoir pour mieux connaître l'un des métaux le plus influent sur l'échiquier stratégique et économique mondial.

Book Description
As the title suggests this book focuses on the extractive metallurgy of cobalt which is rarely treated in a comprehensive manner as cobalt and cobalt-compounds are typically by-products of nickel and copper production. The book is written in French. Introductory chapters cover history, mineralogy, chemical properties as well as reserves and production statistics from 2008/2009. Chapter 4 (Hydrometallurgie du cobalt) is one of the main chapters that includes the leaching behaviour of the element with respect to the form of cobalt feed highlighting the importance of oxidation-reduction reactions. There are references to leaching kinetic models and relevant chemical thermodynamic considerations along with a number of examples of industrial process flow diagrams. Impurity precipitation and solvent extraction are also included in this chapter in a similar style with examples of processing equipment. Chapter 5 is a relatively brief chapter about cobalt-compound product precipitation ending with a summary table qualitatively ranking eight process features. Chapters 6 and 7 address the electrowinning and electrorefining of cobalt respectively. Important fundamental and applied considerations are covered. Chapter 8 is on the pyrometallurgy of cobalt with some description of hydrometallurgical refining options at the end. As with the hydrometallurgy chapter, a number of industrial flow diagrams are provided which is helpful. Chapter 9 is about the final uses for cobalt which is shifting with increasing application for cobalt containing batteries. The Metallurgie Extractive du Cobalt provides a good overview of cobalt from the primary sources to end-use with an emphasis on the metallurgical processing options of which there are quite a few. It is most relevant to metallurgical engineers interested in process development. I appreciated the insight provided into the African scene and picked up some useful references from the citations.

Book Description
Provides a unique survey of the information contained in the patent literature concerning solvent extraction of nickel and cobalt. All the available data from the patent documentation is classified systematically for easy retrieval of authors, patents or assignees. Presented in three parts, the first deals with leaching of nickeliferous or cobaltiferous sources using organic reagents; the second reviews the solvent extraction of nickel or cobalt, or both from solutions; the third covers solvent extraction methods used to remove impurities from solutions containing nickel or cobalt. Cites over 300 patent documents.

Book Description
This book contains information about how main base metals are made, what everyone especially metallurgists, chemists, process and mine engineers should know about their elaboration from the mine to the metallic state.This book is already used by several applied sciences department and engineering schools and universities in the world.Processes are clearly explained and described with more than 100 flow-sheets, sketches and graphs. This book contains common and up-to-date extraction processes and will fill the will to know of many, it will help to have in hand the essential on extractive metallurgy of base metals and some strategic ones.This book is written in a clear and understandable way by an experienced metallurgist engineer and can be read by focusing straight on a particular metallurgy as it is developed metal by metal.All processes are different even if some are similar, you have better to go through to learn or refresh yourself.Roger Rumbu, Met.
