2016-6-13 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. The process of beneficiation of run of the mine ores and subsequent

In fact, tailings characteristics vary greatly and are highly dependent on the ore type, clay mineralogy, and the physical and chemical processes used to extract the economic product. Therefore, a comprehensive understanding of the mechanical properties of mine tailings is critical for the design of a tailing dam.

A tailings storage facility at a gold mine. Spigots are seen going out from a pipe which is transporting the tailings. Mine water. Water is used in many of the processes within the mine and the processing plant. Some processes, such as milling, can use large volumes of water and potentially contaminate it with metals and other harmful elements.
