Mine Tailings Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so proper transportation and disposal are crucial. Consequently, the next step is to

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 known as tailings. This process of product extraction is never efficient, nor is it possible to reclaim all reusable and expended processing reagents and

Regular operations at gold mines adversely affect the environment in several ways. For example, the operation of large mining equipment requires fuel and results in the emission of greenhouse gases. However, potential mine accidents and leaks pose an even greater threat to nearby land and water resources. Contaminated tailings, or waste ore, need to be stored behind a dam; failure of such a
