Comparison of Environmental Impacts of Deep-sea Tailings …
The size of tailings retention facilities varies greatly, but a typical tailings dam is likely to have a surface area of between 1 and 10 km 2. This is a far smaller footprint than DSTP where tailings deposition is usually unconfined and only restricted by the local bathymetric features of the ocean floor (e.g., submarine canyons).

As time goes by, the process of tailing disposal or placement has used various methods of disposal: in the rivers, or on the land with tailings dam. The most popular and widely used method today is the disposal of tailings on the seabed (submarine tailing disposals). Mining companies in Indonesia that use submarine tailing disposals are PT.
