Therefore, the potential to develop acidic conditions in pyrite-rich tailings is very high. Seepage from tailings can be prevented or minimized by placing an impermeable barrier, such as clay, at the bottom of the impoundment before tailings disposal. Many pre-1970s tailings impoundments did not have such barriers.
