What is the primary function of a "tailings" storage facility in mining?

The primary function of a tailings storage facility is to hold waste material from mining operations after the ore has been processed. When ores are mined and processed, the valuable minerals are extracted, leaving behind a mixture of water, minerals, and other materials known as tailings. These tailings must be managed properly to minimize their environmental impact. The facility is designed to contain and stabilize these waste materials, preventing them from contaminating surrounding land and water sources.

In addition to their function as waste storage, tailings storage facilities are carefully engineered to ensure that they are safe and effective in containing the tailings over time. This includes considerations for the structure's design, maintenance, and monitoring to prevent failures and mitigate risks associated with the potential release of toxic substances.
