Abstract: With the increasing mining activities in China, the surrounding eco-environment of mines is faced with unprecedented pressure, including a series of resources, ecological, and environmental problems. This paper introduced the main methods and technical processes for strip mining of typical rare earth ore, summarized the radioactive, heavy metals, fluoride, ammonia, and sulfate contaminations from the mining, and illustrated the impacts and potential hazards of the mining on resources reclamation and utilization, surrounding air, plants, aquatic ecosystems, and soil environment, which could provide scientific bases for the future integrated pollution control and ecological remediation of contaminated environment in rare earth mining areas.
