Oct 04, 2015· What Types of Minerals Do Mining Companies Expect to Extract from the Ocean? Copper, gold, manganese, and even diamonds are all on the list of elements mine operators anticipate recovering from ocean floor mining operations. In fact, most mineral mined on land can be extracted from the world''s oceans.
In short, actual mining of deepocean seabed mineral resources is still some years away. However, for decades now, seabed mining has been happening in coastal waters in depths of up to 150m. If sea mining is allowed ''Different methods are required for the different SMS, nodules and crusts,'' Hein said. ''Four or five methods have been developed
Marine minerals > Natural gas and oil have been extracted from the seas for decades, but the ores and mineral deposits on the sea floor have attracted little interest. Yet as resource prices rise, so too does the appeal of ocean mining. The excavation of massive sulphides and manganese nodules is expected to begin within the next few years.
