What are mine tailings Tailings are the waste products from mining. Mechanical and chemical processes are used to grind up rock into a fine sand to extract the valuable mineral or metal from the rock ore.

Aug 10 2018 · Tailings are a type of rock waste from the mining industry. When a mineral product is mined the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals sometimes through the addition of chemicals it is piled up into 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.
