The main impression of this book is to draw attention to the most advance technologies in silver recovery and recycling from various sources. The state-of-the-art in silver recovery from different sources by hydrometallurgical and bio-metallurgical processing, and varieties of leaching, cementing, reducing agents, peeling, electro-coagulants, adsorbents, electro-dialysis, solvent extraction, ion exchange resins and bio-sorbents are highlighted in this book. It is shown that the major economic driver for the recycling of depleted sources is for the recovery of silver. In order to develop a nature-friendly technique for the recovery of silver from diverse sources, a critical comparison of existing technologies is analyzed for both economic viability and environmental impact were made in this amendment, and silver ion toxicity is highlighted in this book. This book comprises four chapters, each of which is further divided into sections and subsections for the proper convenience and understanding of the work, though extensive work has been reported on silver hydrometallurgy.
