An Economic Way Of Mining Nodules

The Lifting Installation of Manganese Nodules and Pump Test235 Кб. Comparing the tests research and economic technology of slurry pump, cleaning pump, jet pump and air lifting, slurry pump is selected as the lifting method of pilot mining testing ofIn the one way test, the nodules transport directly to a separator with pressure regulation via the feeder, the pump and pipe.

Mining manganese nodules: Potential economic and

This article examines the economic implications of mining or of not mining manganese nodules and summarizes potential ecological consequences. Apart from possible net economic benefits to certain countries, mining the nodules is not regarded as an economic or strategic necessity.

Downloadable (with restrictions)! The recent and renewed interest in deep-sea mining relates to the decrease of ore grades of known land-based deposits, the increasing costs in land-based mining, as well as rising metal prices, and an increased demand for strategic metals. This study examines the economic requirements for future commercial mining projects focusing on manganese nodules.

A “mine site” is defined as an area on the ocean floor where, under specific geological, technical, and economic con-ditions, a single SMnN mining operation (one MSV) can be performed for a period of time (UNOET 1987). A “mining field” is defined as the next smaller unit in a mine site.

Environmental aspects of manganese nodule mining

2017-7-18  The mining of manganese nodules from the floor of the deep ocean has no historical parallel to draw upon for an evaluation of the possible environmental effects. Mining sites will be located thousands of kilometres from land, on the high seas, with 5000 metres of ocean water between the mining platform and the minerals being mined.

A comprehensive approach for a techno-economic

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. The comprehensive approach has been validated using research

1983-6-1  RESOURCES POLICY June 1983 Mining manganese nodules Economic and strategic consequences of not mining nodules The central issue in the debate concerning whether or not it is essential to mine deep-sea nodules in the near future revolves around the potential consequences of not having the nodules as an additional source of supply.

A historical perspective on deep-sea mining for

2019-7-1  Given this international political-economic background and expectations about future resource supply, mining manganese nodules from the ocean floor looked increasingly attractive. Manganese nodules offered a way for the industrialised states to bypass to some degree the developing countries, at least regarding nickel, copper, and cobalt.

Why deep-sea mining is risky for everyone

2020-12-23  Mining creates both a sediment plume on the ocean floor and a “dewatering” plume that is released by the vessel as it dumps everything that has been pumped up with the nodules. A single mining operation, says Smith, can create a sediment plume of 2,000 square km, interfering with the ability of species in that area to feed, mate and survive.
