The current technological challenges mean that engineers are expected to apply the available extraction in the field of extractive metallurgy. Extraction of copper, one of the most used metals, has... More > been practiced since ancient times around the world. Three crucial steps, namely sulphide roasting, leaching of ores and concentrates, and electro-extraction through solvent extraction, are described here with ample details, diagrams, examples and explanations to enlighten practitioners. these techniques are widespread where copper ores are mined. These modes of extraction are applied in operations for many non-ferrous metals from where the interest of this book which enters in the collection of Extractive Metallurgy. Roger RUMBU, Met.

Nowadays, importance of lithium beside cobalt cannot be hidden especially for energy storage systems. Lithium can be found in unexpected area of the world like Zimbabwe, D.R. Congo, Serbia or... More > Afghanistan raising questions on a geopolitical point of view. Some efforts must be done for some countries to reach their true economical potential. From engineering side, a lot of technics are developed and used for the extraction of this commodity of great importance for our era. A great importance must be given to mitigate resources scarcity like recycling. Some developed countries are not investing enough in recycling facilities even if processes are well developed and known. Roger RUMBU, Met. Eng., PPM, TBOM.< Less

Par le concept de métallurgie, nous entendons ici tout ce qui concerne l’extraction des ressources métallifères, leur traitement afin d’aboutir à une forme économiquement intéressante ou techniquement utilisable, en d’autres termes, nous parlons ici de procédés d’élaboration des métaux ou métallurgie extractive. Plusieurs aspects sont décrits dans cet ouvrage en passant par les bases thermodynamiques, l’études des minerais ainsi que de leurs conditions d’extraction, la minéralurgie, l’hydrométallurgie, la pyrométallurgie et l’électrométallurgie. Cet ouvrage permet ainsi de renseigner sur les concepts relatifs à la transformation des matières pour obtenir des métaux, éléments essentiels dans notre vécu ainsi que dans l’économie mondiale.
