Deep sea mining is a mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean's surface.
This is still the area considered of greatest economic potential in the global ocean because of high nickel (Ni), copper (Cu), and Mn contents and the dense distribution of nodules in the area. While the mining of nodules was fully expected to begin in the late 1970s or early 1980s, this never occurred due to a downturn in the price of metals ...

What are some potential problems with mining manganese nodules on the seafloor? The mining of manganese nodules can destruct deep sea habitats and the cost of machinery might not be beneficial economically. There are also unknown effects since no one has ever tried mining on the seafloor. 9. What is the EEZ? The Exclusive Economic Zone, which ...
Kennecott Copper had explored the potential profits in manganese nodule mining and found that it was not worth the cost. On top of the environmental issues and the fact that the profits had to be shared, there was no cheap way to get the manganese nodules off the sea floor.

Other articles where Manganese nodule is discussed: authigenic sediment: Manganese nodules are pebbles or stones about the size of walnuts that are built of onionlike layers of manganese and iron oxides. Minor constituents include copper, nickel, and cobalt, making the nodules a potential ore of these valuable elements. Mining of manganese nodules has been…
Aug 29, 2019· Interest in seabed mining has mostly focused on the iron manganese nuggets (nodules) that are abundant in many areas of the deep sea. These odd objects were first discovered during sailing expeditions in the 1870s and early twentieth century, when the little metal balls were scooped up in bottom survey nets.
Jul 19, 2006· The BGR has carried out a total of eight exploration cruises to the German license area between 2008 and 2016. Five of these cruises focussed primarily on detailed analyses of the manganese nodule resource potential and its economic value as well …
This Bureau of Mines report describes an investigation of factors influencing economic viability of a proposed system to mine and process manganese nodules. The system consists of hydraulic dredging and ammonia leach processing designed to recover three metals: nickel, copper, and cobalt. A ferromanganese recovery plant is a considered option.

polymetallic nodules mining for a sustained development of the resource. 2. Economic considerations Increasing awareness of the distribution and potential of deep-sea minerals such as the ferro-manganese nodules and crusts (Cronan, 2000; Rona, 2003) has kept the world's interest in these
Apr 25, 2018· The expert who first pointed out the economic potential of manganese nodules was John Mero, who audaciously stated that if only 10 percent of the nodules were to be mined, they could provide enough metal to support a world of 20 billion people for thousands of years.

potential (financial and economic) is to have sound estimates of the in-situ value of these deposits, some estimates of the capital and operating costs for production, and full payment of taxes and royalties, factoring in the cost of meeting the full contractual and regulatory compliance necessary
Mine planning of land-based mineral deposits follows well-established methods. The deep sea is currently under exploration, but mine planning approaches are still lacking. A spatial planning tool to assess the techno-economic requirements and implications of manganese nodule mining on deep-sea deposits is proposed in this paper.
Jul 16, 2018· More than one million square kilometers of the abyssal Pacific seafloor have been identified for possible seafloor nodule mining. Manganese nodules are a potential source of copper, nickel, cobalt, iron, manganese and rare earth elements—metals used in electrical systems and for electronics like rechargeable batteries and touch screens.
