Increasing exploration and industrial exploitation of the vast and fragile deep-ocean environment for a wide range of resources e.g., oil, gas, fisheries, new molecules, and soon, minerals raises global concerns about potential ecological impacts 1 1 3 2.

DEEP SEA MINING Deep sea mining is a relatively new, extreme, and dangerous mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules at about 1,400 - 3,700 m below the oceans surface.

2019-10-10these uncertainties requires new technology and new concepts to better understand the resource potential. The prospects of deepsea mining have advanced in fits and starts, first with the manganese nodule boom in the late 1970s and early 1980s, then the Red Sea pilot mining project, and now the likelihood of ...

Commercial-scale mining for polymetallic nodules could have a major impact on the deep-sea environment, but the effects of these mining activities on deep-sea ecosystems are very poorly known. The first commercial test mining for polymetallic nodules was carried out in 1970. Since then a number of small-scale commercial test mining or scientific disturbance studies have been carried out.

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.

Of all the mineral resources considered as potential targets for deep-sea mining, polymetallic nodules also commonly called manganese nodules are probably the most likely commodity to be developed into a commercial operation. As well as containing commerically attractive though variable levels of metals such as nickel, copper and cobalt ...

Mining - Mining - Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...

The global mining industry is under pressure. In the short term, falling commodity prices are squeezing cash flow. Looking ahead, many existing mines are maturing, resulting in the extraction of lower ore grades and longer haul distances from the mine face ore-body-replacement rates are in decline and new-mine-development times are increasing.

The industrialization of the deep sea is expanding worldwide. Increasing oil and gas exploration activities in the absence of sufficient baseline data in deep-sea ecosystems has made environmental management challenging. Here, we review the types of activities that are associated with global offshore oil and gas development in water depths over 200 m, the typical impacts of these activities ...
