Integrating waste management, environmental sustainability, and economic development is a prime milestone in the circular economy. Critical metals recovery from mining tailings and secondary resources has significant potential, with widespread applications in high-tech industries that are critical to modern society and sustainable development. This book discusses technological advances for managing industrial and mining waste through circular economy approaches and successful critical metal recovery from secondary resources. It highlights how reprocessing of mine waste and tailings results in development of critical raw materials that significantly reduce the mining burden and ensure the lucrative use of waste materials. Features: Describes advances in remediation and valorization technologies for mining wastes Details biotechnological methods, cutting edge research, and applications Covers use of waste mining resources for economic growth and novel opportunities Discusses IR4.0 and machine learning methods Includes reports and case studies on mining waste in value-added products and recovery of strategically important critical minerals This book will be of value to researchers and advanced students working in the mining, chemical and environmental engineering, and renewable energy sectors.
