Download or read book Recovery and Recycling of Valuable Metals written by Dariush Azizi and published by Mdpi AG. This book was released on 2022-01-27 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals have always played a significant role in human life, and the current global growth and prosperity are directly dependent on these materials. With the rapidly growing global demand for metals, their extraction from natural minerals (as their primary sources) has been enhanced, causing a significant reduction in the grade and quality of the ores in ore deposits and leading to the production of huge amounts of waste, which requires management. In light of this, new proposals to develop more advanced metal recovery technologies from minerals are needed. Additionally, the huge quantity of waste generated through all steps of metal production is known to be a source of environmental pollution, while its valorization can create value via recycling metals or even though use in the production of other valuable materials. Such waste valorization is also in line with the United Nations' Sustainable Development Goals (SDGs), as well as the implementation of the Paris Agreement. In this regard, the recycling of end-user products in order to reproduce valuable metals can also create significant value and reduce mining activities, and thus, their harmful consequences worldwide. Therefore, research and development in the state-of-the-art technologies for the recovery and recycling of metals are absolutely necessary. The aim of this Special Issue was to collect a range of articles on different aspects of valuable metal recovery and recycling from primary and secondary sources, as well as to decipher all new methods, processes, and knowledge in valuable metal production. We hope that this open access Special Issue will provide a great opportunity to demonstrate the work of researchers working in this area all around the world and help to provide new ideas for researchers who are working in the areas of hydrometallurgy, mineral processing, and waste recycling and valorization.

Download or read book Metals in Wastes written by Karolina Wieszczycka and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-07-23 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals in Wastes is an excellent guide for scientists, students, engineers, chemists, and industrial chemists who are looking for knowledge of the main sources of metals in industrial wastes. Metals are valuable materials that can be recycled again and again without degrading their properties. The recycling of metals enables us to preserve natural resources while requiring less energy to process than the manufacture of new products using virgin raw materials. A team of experts reviews the state-of-the-art and provides the readers not only with a comprehensive in-depth overview of the main composition of wastes but also discloses innovative methods which have been applied for recovery of critical and valuable metals in petrochemical industry, rubber, energy and automotive industries. This know-how could be considered as a useful reference tool for moving towards the zero-waste economy. Additionally, the book describes the economic aspects of metals recovery from various sources. This is essential for those already involved in the metals business and also for the financial, investment and advisory community internationally.
Download or read book Sustainable Utilization of Metals written by Bernd Friedrich and published by MDPI. This book was released on 2020-05-23 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high demand for advanced metallic materials raises the need for an extensive recycling of metals and such a sustainable use of raw materials. "Sustainable Utilization of Metals - Processing, Recovery and Recycling" comprises the latest scientific achievements in efficient production of metals and such addresses sustainable resource use as part of the circular economy strategy. This policy drives the present contributions, aiming on the recirculation of EoL-streams such as Waste Electric and Electronic Equipment (WEEE), multi-metal alloys or composite materials back into metal production. This needs a holistic approach, resulting in the maximal avoidance of waste. Considering both aspects, circular economy and material design, recovery and use of minor metals play an essential role, since their importance for technological applications often goes along with a lack of supply on the world market. Additionally, their ignoble character and low concentration in recycling materials cause an insufficient recycling rate of these metals, awarding them the status of “critical metals”. In order to minimize losses and energy consumption, this issue explores concepts for the optimization concerning the interface between mechanical and thermal pre-treatment and metallurgical processes. Such new approaches in material design, structural engineering and substitution are provided in the chapters.

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 192 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: Critical raw materials (CRM) are used in various applications in different sectors, and their consumption will likely further increase in future. The threats caused by their limited availability and high prices have led to discussion on more efficient use of the resources available. The enhanced recycling of critical raw materials could be a significant opportunity for the Nordic countries.This report focuses on the recycling potential of wastes containing CRMs, analyses of the bottlenecks of recycling, and identifies potential policy instruments to eliminate the barriers or reduce their impact. In order to enhance sustainable recycling, the Nordic countries should improve knowledge of CRM availability, develop new recycling strategies, support demonstration and selected R&D actions, and strengthen Nordic influence on the development of European legislation and standards.
