Mine Tailings Dredges Mine Tailing Dredging Equipment

Mine tailings are the natural byproduct of raw materials mining. As rocks and minerals are crushed and washed, the effluent water carries the dust particles to settling ponds where the material is collected and eventually removed. It is then hauled away for a secondary process or stored for long periods of time.

Mining. The pyrite is then processed to remove the iron, which is sold for a profit. The sulfur-bearing waste material that's left behind after the iron is taken out is then just discarded or piled up on the ground. Before mining, the sulfide materials naturally in the ground pose little threat to the environment.

What does tailings mean? Definitions

Tailings are distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. The extraction of minerals from ore can be done two ways placer mining, which uses water and gravity to extract the valuable minerals, or hard rock mining, which uses pulverization of rock, then chemicals.
