The disposal of copper mine tailings (CMT) in finite containment facilities near mine sites is a serious human safety and environmental management challenge in most copper-producing countries of ...

Copper mines obviously yield copper, but they also produce waste material – tailings – which must be disposed of somehow. In Norway, tailings have often been dumped in fjords as an alternative to disposal on land. The environmental impact of this practice over time is not known.

Oct 04, 2020· 4. Safety hazards. Tailings pond has safety hidden danger, such as collapse, slide. Based on the above problems, the gold tailings disposal methods and comprehensive utilization of gold tailings is extremely urgent. At present, the common gold tailings disposal methods and comprehensive utilization mainly include the following ways:

The engineering properties of tailings are important for the safety evaluation and engineering design of tailing dams. In the present study, laboratory experiments were performed to investigate the geotechnical properties of four different tailings, including two iron tailings (coarse and fine) and two copper tailings (coarse and fine).

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.

Jun 07, 2021· Disposal and Reuse. Some wastes from copper mines can be reused. Mixtures of crushed waste rock have been used to construct embankments, fills, or pavement bases for highways. Some studies have shown that copper tailings can be used in bricks if pyrites are first removed.
