·Citation Longsheng YI Hongcheng MI Qian WU Jin XIA Binghang ZHANG Present Situation of Comprehensive Utilization of Tailings Resources in China[J] Conservation and Utilization of Mineral Resources 2020 40 3 79 84 doi /
·This is an essay in the field of mining engineering Copper tailings are mainly concentrated in east China southwest China and central South China which are stored in dry dumps or wet discharge in tailings pond The lack of multi gradient and multi direction utilization mode brings great threat to the environment and safety around the mining area
·Historically safe containment has been the main goal of tailings management Disposal has taken place in sizable surface impoundments that are enclosed by dams or embankments as well as in subterranean workings and unnatural depressions [10] [11] However the environment and communities are seriously endangered by the inappropriate management
After a long period of extensive mining the amount of domestic minerals has gradually decreased Outdated mining methods lead to a substantial increase in costs while leaving many mine tailings The insufficient utilization of tailings has formed many obstacles to the sustainable development of the industry
·These statistics include iron tailings discharged from mines steel slag and copper slag in smelting slag and a large amount of industrial solid waste such as coal gangue and domestic sludge from
·To enhance the effective utilization of graphite tailings and coal gangue CG both considered typical industrial solid waste materials we synthesized foamed ceramics incorporating these materials The optimization process
Domestic Tailings Production Trends Since 2015 domestic iron ore tailings production has declined mainly due to reduced mining activities However with economic recovery and growing demand for minerals domestic tailings output rebounded to billion tons in 2022 marking a % year on year increase As tailings utilization
·Kai Dong Area of Work Mainly engaged in short process steelmaking of electric arc furnace CO2 resource utilization of iron and steel process energy conservation and environmental protection of metallurgical process combined solid waste disposal and development of process technology related to metallurgical intelligent control
·Meanwhile the engineering practice of tailings resource utilization made a breakthrough Firstly based on the domestic industry statistics combined with the changes in the number of tailings ponds in Yunnan Province the tailings ponds tailings generation and comprehensive utilization of tailings are analyzed
The situations characteristics and status of iron ore tailing resources in China are presented The approaches of comprehensive utilization of iron ore tailings have been analyzed It has been proved that the comprehensive utilization of iron ore tailings is efficient socially beneficial and improves environment situation The scopes of comprehensive utilization of iron ore tailings are
