Book Synopsis Metal Recovery from Electronic Waste: Biological Versus Chemical Leaching for Recovery of Copper and Gold by : Arda Işildar
Download or read book Metal Recovery from Electronic Waste: Biological Versus Chemical Leaching for Recovery of Copper and Gold written by Arda Işildar and published by CRC Press. This book was released on 2018-10-30 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has catastrophic effects on humans and the environment. WEEE contains considerable quantities of valuable metals such as base metals, precious metals and rare earth elements (REE). Metal recovery from WEEE is conventionally carried out by pyrometallurgical and hydrometallurgical methods. In this PhD research, novel metal recovery technologies from WEEE are investigated. Using acidophilic and cyanide-generating bacteria, copper and gold were removed from crushed electronic waste with removal efficiencies of 98.4 and 44.0%, respectively. The leached metals in solution were recovered using sulfidic precipitation and electrowinning separation techniques. Finally, a techno-economic assessment of the technology was studied. This research addresses the knowledge gap on two metal extraction approaches, namely chemical and biological, from a secondary source of metals. The essential parameters of the selective metal recovery processes, scale-up potential, techno-economic and sustainability assessment have been studied.

Available in PDF, EPUB and Kindle. Book excerpt: V. I. MATKOVICH During the meeting of the International Symposium on Boron held in October, 1972 in Tbilisi, U.S.S.R., the idea was proposed to assemble a review of boron and refractory borides by the specialists present. The advantages of such a work were immediately apparent. Such diverse applications of borides as in protective armor, nuclear reactors, coat ings, reinforcement, etc. can hardly all be presented in sufficient detail by a single author. On the other hand it was also recognized that with so much specialization, some areas of interest may not be covered. Within the last decade or two a number of areas have been developed in which the use of refractory borides is growing and improvements are being actively explored. Thus, a number of borides have considerable potential as reinforcing material for plastics or light metals, though only boron fibers have been firmly established up to the present. Ap plication of flakes and films for two-dimensional reinforcement appears attractive, although the high cost of materials and development repre sents a considerable barrier. A number of borides have been used to manufacture lightweight protec tive armor. In this area relatively fast changes seem to be taking place as improvements in performance and weight are made. Boron carbide has found considerable use in this application and new developments exploit the light weight of beryllium borides.

This book was released on 2023-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce livre se penche sur le rôle des richesses en ressources naturelles dans la transformation économique de l’Afrique et évoque les enjeux de la transition sobre en carbone pour les économies riches en ressources. La richesse en ressources constitue en effet un facteur clé dans la majeure partie des économies subsahariennes, dont le sol recèle un important potentiel inexploité. Les gisements souterrains de métaux, minerais, pétrole et gaz représentent des sources prépondérantes de recettes publiques et de revenus d’exportation, tout en offrant des possibilités de développement dans la plupart des pays du continent. En dépit de réserves conséquentes, la conversion de la richesse du sous-sol en prospérité durable n’a pas été pas couronnée de succès. Depuis la baisse du prix des matières premières constaté en 2014, la croissance des pays d’Afrique riches en ressources est plus lente que le taux de croissance moyen observé dans la région. Il est donc vital pour son avenir économique que le continent africain puisse tirer profit de ses richesses en ressources naturelles et ainsi favoriser sa transformation économique. Alors que le monde s’éloigne des combustibles fossiles conformément aux engagements pris dans le cadre de l’Accord de Paris, les pays africains riches en ressources voient surgir de nouveaux risques et de nouvelles opportunités. Des estimations récentes suggèrent que 80 % des réserves de combustibles fossiles attestées dans le monde doivent rester enfouies pour atteindre les objectifs de Paris; or, une grande partie de ces réserves «échouées» se situent en Afrique. Pour les nombreuses économies africaines qui dépendent de l’extraction et de l’exportation du pétrole, cette problématique des actifs «échoués», et par là -même, de «nations échouées», a des implications considérables. Mais cette transition énergétique va également avoir pour effet d’augmenter la demande en intrants de matières premières indispensables aux technologies des énergies vertes. La transition entre combustibles fossiles et énergies vertes devrait ainsi générer une demande de 3milliards de tonnes de minerais et de métaux nécessaires au déploiement des technologies à énergie solaire, éolienne et géothermique. Une question se pose alors: comment les économies africaines peuvent-elles pleinement saisir ces opportunités tout en gérant les risques inhérents aux combustibles fossiles, dans un contexte où leur demande est vouée à décroître? Les ressources naturelles, un enjeu clé pour l’avenir de l’Afrique aborde ces thèmes et offre aux décideurs politiques des pistes pour gérer les écueils de l’incertitude au cours des années à venir.

Book Synopsis Bibliography of Magnetic Materials and Tabulation of Magnetic Transition Temperatures by : T. F. Connolly
Download or read book Bibliography of Magnetic Materials and Tabulation of Magnetic Transition Temperatures written by T. F. Connolly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This referenced compilation of magnetic transition temperatures represents (with the Addendum) papers actually received by the RMIC through May 1972 and consists of two lists (alphabetical by compounds), one for Curie and one for Neel temperatures. Where different values appeared in the literature for a single compound, all are listed with sepa rate references given for each. There is no attempt at critical evaluation, which, except for a few welt-studied and well characterized materials, would hardly be worth the effort. All that one can say for most of the compounds is that for a given material with a certain (or all too often uncertain) history of preparati'on and treatment, stoichiometry, homoge neity, and chemical or structural purity a magnetic transition was indicated at the temperature(s) listed. Only when the reasons for different values are explicitly stated in the literature do they appear as brief comments in the body of the lists. In order to include the most recent data, and to eliminate the delay involved in recomposition of the lists, an addendum is provided. While this requires the perusal of two lists rather than one, it does ensure that the compilation represents the entire RMIC collection at the moment of going to press. The 2478 references are restricted to those papers specifying a Curie or Neel temperature and do not reflect the complete magnetics literature even for the materials listed.
