Abstract
The authors review the methods of dust emission suppression at operated and abandoned tailings storages. The environmental impact of mineral dust particles and the after-effects are greatly varied. Dust suppression in surface layer of tailings ponds can use the most widely applied chemical methods, as well as mechanical and biological methods. The requirements imposed on binding agents are efficiency, dust catching, longevity and the environmental safety. Dust suppression control can utilize natural climatic events, e.g., seasonal freezing-thawing of tailing surface. The described engineering solutions concern techniques and equipment for spreading suitable chemical agents for dust suppression at overburden dumps and tailing storage facilities at mining and processing plants.
