Manganese Nodule an overview | ScienceDirect Topics

Manganese Nodule Manganese nodules are usually located at depths below 4000m and are composed primarily of manganese and iron and elements of economic interest, including cobalt, copper, and nickel and make up a total of around 3% by weight (Margolis and Burns, 1976)The recent and renewed interest in deepsea mining relates to the decrease of ore grades of known landbased deposits, the increasing costs in landbased 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 Beside the common measures ofEstimating the economics of a mining project on seafloorBeside seafloor manganese nodules (SMnN) and crusts (SMnC), massive sulfides (SMS) have the highest economic potential (Hein 2016; SPC 2016;Sharma 2017) SMnN are solid concretions of manganese(PDF) Manganese Nodules ResearchGate

Environmental aspects of manganese nodule mining

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 minedManganese Nodule Mining and Economic Rent Nina W Cornell Recommended Citation The actual number of potential mining sites is unknown except perhaps to the companies considering the industry It seems likely, however, that the total number of commercially viable sites are limited and that some of them are more valuable than othersManganese Nodule Mining and Economic Rentpolymetallic nodules mining for a sustained development of the resource 2 Economic considerations Increasing awareness of the distribution and potential of deepsea minerals such as the ferromanganese nodules and crusts (Cronan, 2000; Rona, 2003) has kept the world’s interest in theseDeepsea mining: economic, technical, technological and
