Xinhai | Reliable Tailings Storage Solutions from Design to Construction

Tailings storage facility is a storage facility for mine tailings or other industrial waste generated during mineral processing. It is typically enclosed by a tailings dam and used to store tailings from metal or non-metal mines. Tailings storage facility generally includes a tailings disposal system, a drainage system, and a return water system. Based on terrain, tailings storage facility can be classified into valley-type, hillside-type, flatland-type, and river-interception-type tailings storage facility. 

As a critical facility in mining operations, tailings storage facility not only facilitate resource recovery but also serve as crucial environmental protection projects for mining companies, effectively preventing untreated tailings from being released into the natural environment.
