What are tailings storage facilities | BHP
Tailings are the left-over materials from the processing of mined ore. They consist of ground rock, unrecoverable and uneconomic metals, chemicals, organic matter and effluent from the process used to extract the desired products from the ore. Tailings are stored in tailings storage facilities (TSFs). TSFs are dynamic structures that are ...
