gold mining equipment in deep water

Deep sea mining - Wikipedia
Deep sea mining is the extraction of minerals from the ocean floor found at depths of 200 metres (660 ft) to 6,500 metres (21,300 ft). As of 2021, the majority of marine mining efforts were limited to shallow coastal waters, where sand, tin and diamonds are more readily accessible. It is a growing subfield of experimental seabed mining. Three types of deep sea mining have generated

Deep Sea Ocean Mining Seafloor Dredging Operations
Subsea mining, or deep sea mining, is a method of retrieving minerals from the ocean floor. Deepsea mining operations typically occur at depths of 4500 ft. to 12,000 ft. around areas with metallic nodules, as well as areas with high levels of geothermal activity. These geothermal vents have a tendency to create globular deposits of valuable ...

Beyond the 1850s Gold Rushes: Mining Technology from the
The 1890s mining boom coincided with the introduction of a new form of alluvial gold mining, called pump, or jet elevator, sluicing. This involved hosing the face of a gully away, then puddling up the resulting wash dirt and elevating it by pressurised water into raised sluice boxes, from whence it passed over a series of ripples where the gold was captured.
