Deep sea mining involves removing valuable materials from the ocean floor using excavator vehicles and control vessels. It is a complex and expensive process that has raised environmental concerns. The method was first introduced in the 1960s but was largely abandoned until the 2000s when it became a viable option again. The process involves the use of remotely operated vehicles and can occur through the Continuous Line Bucket or hydraulic suction system methods.
Deep sea mining is the process of removing valuable materials such as metals and ores from deposits located on the ocean floor or the bottom of other large bodies of water. This method of mining is relatively new compared to land-based mining, and the environmental impact is a concern among conservationists and governments, as well as industries that depend on oceans and waterways. Deep sea mining is a complex and expensive process involving an excavator vehicle on the seabed and a control vessel floating on the surface of the water, as well as some sort of interface to connect the two.
When the deep-sea mining method was first introduced in the 1960s, research teams from many countries began exploring the possibility of extracting valuable materials from the ocean floor. Some popular sentiment at the time suggested that the abundance of precious materials would outweigh the costs of the mining process, but most research teams have found this to be false. The idea of deep sea mining was largely abandoned for several decades, but in the 2000s the mining process became a viable option again and companies began developing methods to acquire the materials buried beneath the water bodies.
The process involves the use of remotely operated vehicles, or ROVs, which are submerged in water until they reach the bottom of that body of water. A control vehicle, usually a vessel, is positioned above the ROV on the water surface. The ROV will extract samples and send those materials to the surface for analysis. This process allows miners to find a potential mining site, and once a site is found, mining can begin.
Mining can occur in two ways during deep sea mining. The Continuous Line Bucket (CLB) features a series of buckets that will pick up materials and deliver them to the surface. Another method, known as a hydraulic suction system, involves the use of a series of long tubes or hoses that extend deep to the surface of the ocean or body of water. The hose sucks surface material through the hose and another hose returns the excess material to the seabed. Deepwater mining companies usually prefer the CLB method, although it’s not always feasible.
