Book Description
Acquiring precious metals is an important issue within the Department of Defense when producing and sustaining major weapons systems. Due to precious metal shortages, effective deployment of the national defense preparedness program is in jeopardy in case of serious or continuous national emergency. The overall objective of this research study was to explore and determine the benefits of silver recycling. An extensive literature review was necessary to understand the Defense Logistics Agency Precious Metals Recovery Program. Through extensive research of the Precious Metals Recovery Program, it is evident that there are substantial cost savings which transfer into huge benefits resulting from recycling silver. Precious metals are vital in satisfying the United States' contractual and specification requirements needed for strategic arms, ammunition and equipment. Recycling silver is a valid way of satisfying these requirements. (Author).

Book Description
WEEE Recycling: Research, Development, and Policies covers policies, research, development, and challenges in recycling of waste electrical and electronic equipment (WEEE). The book introduces WEEE management and then covers the environmental, economic, and societal applications of e-waste recycling, focusing on the technical challenges to designing efficient and sustainable recycling processes—including physical separation, pyrometallurgical, and hydrometallurgical processes. The development of processes for recovering strategic and critical metals from urban mining is a priority for many countries, especially those having few available ores mining. Describes the two metallurgical processes—hydro- and pyro-metallurgy—and their application in recycling of metals Provides a life cycle analysis in the WEEE recycling of metals Outlines how to determine economic parameters in the recycling of waste metals Discusses the socio economic and environmental implication of metal recycling

Book Description
Recycling of waste from electrical and electronic equipment (WEEE) traditionally focuses on large quantities of waste materials such as plastics. However, some product groups in the WEEE contain hidden treasures in the form of critical metals. This project assesses the critical metals’ waste handling as part of five selected product groups, in the Nordic region. The environmental and economic benefits from the recycling of these metals currently and in the near future is quite substantial, mainly due to the presence of significant quantities of gold in the selected products.In order to contribute further to the circular economy concept, the Nordic countries should pay attention not only to quantitative but also to qualitative aspects of recycling, in order to capture recyclable materials that, although in small quantities, their recycling brings a high economic and environmental value.

Book Description
Silver holds three world records; it has the lowest contact resistance, highest electrical conductivity and the best thermal conductivity of all metals. The element's physical strength, brilliance and malleability leads to its many uses from electronics to optical applications.A new 'silver rush' has occurred following the recent discovery that silver, when divided to form particles at the nano scale, can take on new properties. Meanwhile, there has been an increase in regulations against environmental pollution of silver ions toxicity, which have caused numerous diseases and disorders in the marine, microbial, invertebrate and vertebrate community (including humans). Both of which have led to a great interest in silver recovery for both environmental toxicity and an economic point of view.Comprised of ten chapters, this book draws attention to the most advance technologies in silver recovery and recycling from various spent sources, which will appeal to research scientists and metallurgists. The state of the art in recovery of silver from different sources by hydrometallurgical and bio-metallurgical processing and varieties of leaching, cementing, reducing agents, adsorbents, and bio-sorbents are highlighted in this book.

Book Description
The rapid revolution in modern industry has led to a significant increase in waste at the end of the product lifecycle. It is essential to close the loop, secure resources, and join up the circular economy. This book provides a detailed review of extraction techniques for urban mining of precious metals including gold, silver, and the platinum group. The merits and demerits of various extraction methods are highlighted, with possible suggestions for improvements. The feasibility of hybrid extraction techniques, as well as the sustainability and environmental impact of every process, is explored. Offers a comprehensive review of different techniques used in recycling technology for urban mining of precious metals Describes the concept of urban mining and its correlation with circular economy Discusses feasibility of precious metal extraction and urban mines scope and their potential Explains the subject in-context of sustainability while describing chemistry fundamentals and industrial practices Provides technical flow sheets for urban mining of precious metals with diversity of lixiviant This book is aimed at graduate students and researchers in extractive metallurgy, hydrometallurgy, chemical engineering, chemistry, and environmental engineering.
