Deep sea tailing

Dec 02, 2019 Instead, deep-sea tailings placement (DSTP) has become more popular. Development and Recent Status of Deep-sea Tailings Placement. Currently there are fifteen mining operations around the world using deep-sea tailings placement (Morello et al. 2016). Typically, the tailings are disposed below the surface euphotic zone (~ 50–100 m) in areas

    Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 meters or greater. As of 2021, the majority of marine mining efforts are limited to shallow coastal waters only, where sand, tin and diamonds are more readily accessible. There are three types of deep sea mining that have generated
