Download or read book Element Recovery and Sustainability written by Andrew Hunt and published by Royal Society of Chemistry. This book was released on 2013 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased consumption of electronic equipment has brought with it a greater demand for rare earth elements and metals. Adding to this is the growth in low carbon technologies such as hybrid fuel vehicles. It is predicted that the global supply of rare earth elements could soon be exhausted. A sustainable approach to the use and recovery of rare earth elements is needed, and this book addresses the political, economic and research agendas concerning them. The problem is discussed thoroughly and a multi-disciplinary team of authors from the chemistry, engineering and biotechnology sectors presents a range of solutions, from traditional metallurgical methods to innovations in biotechnology. Case studies add value to the theory presented, and indirect targets for recovery, such as municipal waste and combustion ash are considered. This book will be essential reading for researchers in academia and industry tackling sustainable element recovery, as well as postgraduate students in chemistry, engineering and biotechnology. Environmental scientists and policy makers will also benefit from reading about potential benefits of recovery from waste streams.
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.
Download or read book Metal Recycling Experience at Los Alamos National Laboratory Reuse Release and Recycle of Metals from Radiological Control Areas written by and published by . This book was released on 1997 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 15% of the Low-Level Waste (LLW) produced at Los Alamos consists of scrap metal equipment and materials. The majority of this material is produced by decommissioning and the modification of existing facilities. To reduce this waste stream, Department of Energy Headquarters, EM-77 Office, sponsored the Reuse, Recycle, and Release of Metals from Radiological Control Areas High Return on Investment (ROI) Project to implement recycle, reuse, and release of scrap metal at the laboratory. The goal of this project was to develop cost effective alternatives to LLW disposal of scrap metal and to avoid the disposal of 2,400 m3 of scrap metal. The ROI for this project was estimated at 948%. The ROI project was funded in March 1996 and is scheduled for completion by October 1997. At completion, a total of 2,400 m3 of LLW avoidance will have been accomplished and a facility to continue recycling activities will be operational. This paper will present the approach used to develop effective alternatives for scrap metal at Los Alamos and then discuss the tasks identified in the approach in detail. Current scrap metal inventory, waste projections, alternatives to LLW disposal, regulatory guidance, and efforts to institutionalize the alternatives to LLW disposal will be discussed in detail.
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 In Situ Recovery Remediation of Metals written by Drummond Earley III and published by Society for Mining, Metallurgy & Exploration. This book was released on 2020-03-27 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current trends in mining are driving the demand for subsurface extraction technologies with low surface impacts that protect surface and ground water. Moreover, the necessity for sustainable mineral extraction technologies has increased as regulatory restrictions and technical challenges to traditional mining grow with production from deeper and deeper remaining metal resources. This book provides a state-of-the-art synopsis of in situ metal recovery and remediation technologies based on both research and commercial projects. In situ recovery uses fluid-based metal dissolution and recovery to extract one or more commodities from a largely intact rock mass using similar processes that create ore deposits. The fluid is circulated through ore by gravity and/or pumps using injection and recovery wells. A processing facility is usually established at the surface of the operation to extract the commodity of interest. The barren fluid is then recirculated back into the recovery circuit. In situ remediation uses similar wellfield technology and chemical processes to stabilize metal contaminants by injecting agents that form stable solids or less toxic species when combined with a contaminant. The fluid depleted in the stabilizing agent is then pumped back to the surface and regenerated. In situ mining or recovery has been successfully applied to several commodities, including uranium, sulfur, evaporites, and copper, which have favorable chemical properties and deposit types for in situ recovery.

Download or read book Hazardous Waste Reducation in the Metal Finishing Industry written by PRC Environmental Management, Inc and published by William Andrew. This book was released on 1989-12-31 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: "From the Foreword: " This book presents the results of a waste audit study for the metal finishing industry. The study, carried out for the State of California but applicable for metal finishers elsewhere, identifies opportunities for waste reduction available to the metal finishing industry and develops procedures that can be used by metal finishers to assess their own waste reduction opportunities. The study emphasizes technologies available to small- and medium-sized metal finishing plants. Typically, these shops operate a variety of physical, chemical, and electrochemical processes. Chemical processes include degreasing, cleaning, pickling, etching, coating, and electroless plating. Electrochemical processes include plating and anodizing. The tasks included in the study were: (1) selecting metal finishing plants to include in the study, (2) performing a waste audit at each selected plant, (3) developing recommendations for implementing waste reduction technologies at each audited plant, (4) discussing with facility representatives the feasibility of implementing the waste reduction recommendations, and (5) developing this waste audit study report and methodology. The study identifies three categories of waste reduction technologies that are available to metal finishers: (1) source reduction, (2) recycling and resource recovery, and (3) alternative treatment. The costs associated with implementing these technologies range from a few hundred dollars for making simple improvements in housekeepiing and minor process modifications to tens of thousands of dollars for installing recovery or treatment units. The benefits realized from implementing such improvements include reductions inmaterial purchase and waste disposal costs, as well as reduction in the liability
