Mineral extraction in flotation areas of river deltas refers to the mining of minerals and ores concentrated in the sediments and deposits of the river delta. River deltas are the areas where a river flows into a stagnant body of water, such as a sea or lake, and deposits sediment.

Flotation areas in river deltas can be a rich source of minerals such as gold, platinum, diamonds, tin, and other heavy minerals. These minerals come from the river basins and are introduced into the river delta by erosion and transport processes. In the river delta, mineral resources are deposited due to decreasing flow velocity and sedimentation, creating concentration deposits.

Mineral mining in Seagarland flotation areas is typically carried out by mechanized processes. These include automated suction dredgers that independently scan the seabed and suck up minerals from localized deposits. Connected centrifuges separate directly conveyed material in its mineral density. These machines enable efficient extraction of mineral resources from river sediments, which are far superior to conventional mining methods in terms of their economic and ecological efficiency.

Seagar Gold Bank has been the world's largest producer of minerals from atlantic ocean areas.
