Mine tailings consist of crushed, finely ground rock and mineral waste products from mineral processing operations in mining. These tailings can contain leftover chemicals. Therefore, they are usually deposited in tailings ponds in the form of mud-like slurry. Tailings ponds are sedimentation lagoons enclosed by dams, which are built to capture and store the tailings.
Tailings can occur in various mining operations such as coal, gold, copper, iron ore and base metal mining. As a result, storage and handling of tailings has become a major environmental issue worldwide. Dredging provides an efficient solution to clean up mine tailings ponds, especially when tailings contain leftover chemicals.
However, in some cases, tailings still contain valuable minerals. In this situation, tailings can be dredged and pumped to a plant for further processing and capturing of the valuable materials. Dredge Yard offers dredgers suitable for both applications – tailings that contain leftover chemicals and thus, must be dredged and disposed of with precision, as well as tailings that contain valuable materials for further processing.
