Tailings Wikipedia
In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being 展开Tailings consist of ground rock and process effluents that are generated in a mine processing plant Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream Tailingsfo What Are Tailings? Their nature and Tailings is a common byproduct of the process of extracting valuable minerals and metals from mined ore They usually take the form of a liquid slurry made of fine mineral particles, created About Tailings – Global Tailings ReviewMine tailings are a waste material from the mining industry generated during the separation of valuable minerals from invaluable waste [45] Recent investigations on onepart AAMs used Mine Tailing an overview ScienceDirect Topics
