The Rare Elements: Occurrence and Technology (Topics in Inorganic & General Chemistry) - Tapa dura

Sinopsis

The Rare Elements examines the geological and geochemical aspects of rare elements and describes the different means of recovering them from their natural sources, from semi-finished products and from industrial wastes. After a chapter on the geology and geochemistry of different types of mineral deposits, further chapters deal with the mechanical and chemical beneficiation of ores, and chlorination in rare metals recovery. The theoretical and practical aspects of solvent extraction in connection with the recovery of rare elements are dealt with in great detail in a chapter which reviews a large number of extraction systems and is illustrated by forty solvent extraction diagrams. The final chapter describe pyro- and hydro-metallurgical procedures for recovering the individual elements from their sources, especially from those containing very small or even trace quantities. The value of the book lies in the fact that much of the text is devoted to the hydrometallurgical and solvent extraction techniques used to recover rare elements from sources hitherto regarded as commercially unviable, e.g. from low-content natural sources and from industrial wastes.
