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. ...

Manganese nodules: desired mineral resource and

Here, in an area of five million square kilometres, manganese nodules are abundantly found on the seabed. Their metal content offers a potential for commercial deep-sea mining. In recent years mineral raw materials from the deep sea have become the focus of some countries and companies in order to secure their supply with high-tech metals.

Manganese nodules « World Ocean Review

The mining, pumping and cleaning of the manganese nodules creates noise and vibrations, which disturb marine mammals such as dolphins, and could force them to flee from their natural area. The sediment-laden water produced by the cleaning of manganese nodules is released into the sea from the ships. A sediment cloud is also created here.

Estimating the economics of a mining project on

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.

The economics of mining seabed manganese nodules:

2019-7-24  We present an economic appraisal and strategy for mining of nodules from the Indian Ocean Nodule Field- one of the four economically potential areas in the world oceans. In contrast to the prevailing perception of non-viability of nodule mining, our analysis indicates a fair degree of economic feasibility and commercial sustainability to mine ...

2020-8-19  Manganese Nodules. An additional potential source of manganese is the ferromanganese nodules and crusts that occur on the seafloor in many parts of the world’s oceans. These bean- to potato-sized nodules are currently the target of exploration and research, mostly focused on the equatorial Pacific Ocean. If production of these nodules proves ...

benefits of mining manganese -

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.
