Book Description

Modern industry is revolutionizing fast which has led to a significant increase in waste at the end of product lifecycle and it is essential to close the loop, secure resources and join the circular economy. This book provides a detailed review of extraction techniques for urban mining of precious metals like gold, silver and platinum group. Periodical growth levels of spent sources, their management necessities and correlation with circular economy are described in detail. Merits and demerits of various extraction methods are highlighted with possible suggestions. Feasibility of hybrid extraction techniques and environmental impact of every process, and its sustainability is explored.
