    Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward finding alternate uses.

Tailings dams were also not needed in most cases, as operations were relatively small compared to modern operations today. Due to the development in processing methods and mine equipment, operations are now able to mine deposits well into lower-grade material, resulting in an increase in mining process fines.

    Tailing ponds are often somewhat dangerous because they attract wildlife such as waterfowl or caribou as they appear to be a natural pond, but they can be highly toxic and harmful to the health of these animals.

  • Tailing Ponds IDE Technologies

    In the mining process, ore mills generate huge amounts of waste, called tailings. These are most commonly dumped into ponds created from naturally existing valleys, and secured by dams.
