Book excerpt: La dénomination "Terres Rares" est évidemment des plus intrigantes. Les métaux de ces terres rares ne sont pas si rares mais c'est plutôt leur métallurgie ou leur extraction métallurgique qui a fait que ces métaux sont qualifiés de métaux de terres rares.La présence des terres rares dans l'écorce terrestre est relativement importante paradoxalement.Comme pour tous métaux stratégiques, les puissances industrielles et économiques comme les Etats-Unis s'inquiètent de ne plus avoir la main mise sur ces métaux et sur leur métallurgie les rendant ainsi dépendants pour leur propre développement, leur sécurité industrielle, militaire et économique.Ce nouvel ouvrage de métallurgie extractive cerne les terres rares de leur découverte à leur utilisation particulière en passant par leur production.Roger RUMBU, Met. Eng., PPM, TBOM.

Les métaux de ces terres rares ne sont pas si rares mais c'est plutôt leur métallurgie ou leur extraction métallurgique qui a fait que ces métaux sont qualifiés de métaux de terres rares. La présence des terres rares dans l'écorce terrestre est relativement importante paradoxalement. Compte-tenu de leur utilité, la gestion et la production des terres rares suite à leur monopolisation par la Chine fait couler beaucoup d'encre dans le domaine de la sphère stratégique et économique. Des industriels occidentaux ont commis l'erreur d'abandonner cette métallurgie que les chinois ont pris soin d'acquérir, de maintenir et de développer.Comme pour tous métaux stratégiques, les puissances industrielles et économiques comme les Etats-Unis s'inquiètent de ne plus avoir la main mise sur ces métaux et sur leur métallurgie les rendant ainsi dépendants pour leur propre développement, leur sécurité industrielle, militaire et économique.Ce nouvel ouvrage de métallurgie extractive cerne les terres rares de leur découverte à leur utilisation particulière en passant par leur production.La crise du cobalt de 1977 n'a pas secoué la terre, la crise des terres rares en 2012 l'a fait.

Available in PDF, EPUB and Kindle. Book excerpt: Mining operations are the key elements in this time of technical changes and development. Transport, housing, different infrastructures are requiring more and more mining resources. the release of a new smartphone or tablet, the top self-driven electrical, the rocket program are all felt in the womb of the earth somewhere in all continents and very soon in the moon. Even a new secured banking note or a pacemaker have their roots in the mines. Mining resources have not been all evaluated, many are estimated explaining why since the man as started digging, many resources are still available leading more and more people investing in mining operations to fill the needs of this world in perpetual development. This introduction to Mining Business Projects is a tool, a must have to help potential junior miners to make the right path in the ventures of mining operations. Mining operation is a tremendous story to share, please go for it. Roger Rumbu, Met. Eng., PPM, TBOM.

Book excerpt: Refractory metals are a class of metals that are extraordinarily resistant to heat and wear making them more expensive to be obtained.Refractory metals are somehow rare compared to base metals.Refractory metals are particular as they can withstand very tough operating conditions. These qualities come from their particular properties rendering difficult their processing that we will describe in this book from heavy sands processing, especially for titanium, zirconium, tungsten, molybdenum, vanadium, and rhenium.Roger Rumbu, Met.

Download or read book Review on Copper Hydrometallurgy written by Roger Rumbu and published by Lulu.com. This book was released on 2019-01-28 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 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.
