Research on comprehensive utilization status and mode of tailings resources

Comprehensive utilization of tailings resources is important.Compared with foreign countries,tailings utilization speed in China is slower,and tailings resources are dominantly used in filling mined empty area.According to estimation and analysis of tailings resources economic performance in China,the tailings quantities that can be recovered and reprocessed only occupy 15% of total tailings quantities.The main utilization mode of tailings resources in the future in China will be tailings reprocessing,being used as building materials,and being used in filling mined empty area.The economic policy about tailings utilization should be adjusted to resolve environmental problems of tailings resources.
