Tailings

Tailings dams are built gradually over time, as the mine produces more waste and hydro dams are constructed all at once. This means that safety oversight can change significantly if the mine changes operators, if the type of ore changes as the mine reaches deeper deposits, or if the mining company comes under economic pressure.
