Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain. This book reviews current status and future trends in the recycling and reuse of mineral and metal waste and also details the policy and legislation regarding the waste management, health and environmental impacts in the mining, beneficiation, metal extraction and manufacturing processes.
This book is a useful reference for engineers and researchers in industry, policymakers and legislators in governance, and academics on the current status and future trends in the recycling and reuse of mineral and metal waste. Some of the key features of the book are as follows:
- Holistic approach to waste generation, recycling and reuse along the minerals and metals extraction.
- Detailed overview of metallurgical waste generation.
- Practical examples with complete flow sheets, techniques and interventions on waste management.
- Integrates the technical issues related to efficient resources utilization with the policy and regulatory framework.
- Novel approach to addressing future commodity shortages.
