Acid Mine Drainage

Acid mine drainage (AMD) is essentially the flow of water polluted with metals and other substances from existing/old mining areas and is considered to be one of the sources of pollution. A wide range of technologies are available for preventing AMD generation and/or treating AMD before discharge, but there is a shift towards recovery of industrially useful materials and products from AMD. Acid Mine Drainage: From Waste to Resources explores novel methods developed for the reuse and/or recovery of industrially useful materials from AMD including discussing generation, prediction, prevention, and remediation processes. It includes legislation and policy frameworks governing AMD and its environmental/health impacts. - Provides a detailed overview of the mining operations and discusses the geochemical and hydrogeological context of acid mine drainage AMD formation, prediction and impact - Presents a holistic approach to AMD generation, prediction, prevention, and remediation processes - Presents exclusive material on reuse, recycling, and recovery of industrially useful materials from AMD - Gives a detailed overview of the legislation and policy regulatory framework governing the management of AMD - Analyses the effects of AMD on the environment and health This volume is aimed at researchers and professionals in metallurgical engineering, chemical engineering, environmental engineering, and mining engineering, including policy makers.
