Very High

Manganese nodules on deep ocean floors have been interested in as future metal resources these forty years. The Total Materials Requirement (TMR) of the conventional proposed mining method, however, is very high because of the much lifted water with the nodules from the seafloor to the sea surface and the longer transportation from the mining site to the smelting plant. An innovative conceptual design of the TMR-less mining system is presented. The economy is examined and compared with the one of the conventional method.

This paper considers the mining of manganese nodules from the deep ocean at up to 5000 m, drawing attention to the essential need for a satisfactory legal regime under which mining companies can operate with security. The necessary exploration that has to be carried out before large investment can be made is indicated and the type and size of mining site required are determined. The paper also considers the equipment required to collect, lift and transport the nodules. The most likely form of collection and lift is hydraulic but there are considered to be substantial development problems still to be solved. This indicates the need for large scale tests before the final decision on the mining system can be completed. The paper describes briefly a test collector operated in late 1974 and early 1975. A brief description of the possible environmental problems is also included.
