Mining waste management: The importance of Tailings Reprocessing Tons of excavated material are extracted every day in mines around the world but only a small percentage contains the wanted mineral. This process is called ore grade. Have you ever wondered where the leftover material goes once the valuable part has been picked out?
ASTM's waste management standards provide the guides, practices, and test methods pertinent to the process of handling residential, commercial, and industrial wastes. This process involves the collection, transport, processing, and recycling or disposal (whichever is applicable) of waste materials for health, environmental, and/or aesthetic purposes.
The Kittila mine is located in the Lapland region of northern Finland, approximately 900 km north of Helsinki and 150 km north of the Arctic Circle.
