This book covers issues pertaining to uranium tailings with special reference to consolidation of radioactivity including systematic ecological strategy for consolidation of radionuclides in uranium tailings. It discusses sustainable consolidation of radioactivity and checks the migration of unextracted uranium from tailing piles to plants and atmosphere supported by a case study from a uranium mine. It provides simple ecological solutions for the remediation of radioactivity in mill tailings.
Features:
- Provides insight into the application of applied ecology for bioremediation of radioactive wastes.
- Discusses species selection criteria for tailings radioactivity consolidation.
- Explains safe treatment of the tailings of radioactive ore processing plants.
- Illustrates the role of ethnobotany in the selection of the most appropriate species to effectively use in bioremediation.
- Focuses on experimental outcomes.
This book is aimed at researchers and professionals in mining engineering, applied geology, nuclear tailings and environmental protection.
