Mining waste is one of the largest waste streams in the EU. It can contain large quantities of dangerous substances.
Mining waste comes from extracting and processing mineral resources. It includes materials such as topsoil overburden (which are removed to gain access to mineral resources), and waste rock and tailings (after the extraction of the valuable mineral).
Some of this waste is inert and unlikely to damage the environment. However, mining waste can also contain large quantities of dangerous substances, such as heavy metals. Extracting and processing metals and metal compounds can result in acid or alkaline drainage.
In addition, tailings management is risky, and often involves residual processing chemicals and elevated levels of metals. Tailings are often stored in heaps or in large ponds surrounded by a dam. These can collapse, with disastrous consequences and a lasting impact on human health, the economy and the environment.
Properly managing mining waste will also ensure the long-term stability of disposal facilities. It will prevent or minimise water and soil pollution arising from acid or alkaline drainage and the leaching of heavy metals.
EU rules aim to prevent or reduce any adverse effects on the environment due to the management of mining waste.
