Mining Waste Management: Reprocessing Tailings

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? The answer is as simple as alarming.
