METHOD OF PRODUCTION OF FERROMANGANESE CONCRETIONS FROM SLUDGE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC E21C50/00 

Abstract RU 2562304 C1

FIELD: mining.

SUBSTANCE: minerals (concretions) separated from bottom during movement of the mining device towed by the tower vessel are taken to the reception vessel in the form of grid from high strength plastic fitted with lifting vessels and cylinders with compressed air, at filling of the reception vessel it moves by gravity from the bottom of the mining device to the soil, and on its place another reception vessel moves, which until this moment is located in the cartridge mounted in the upper part of the mining device and connected with the previous reception vessel by flexible rods, after that during further movement of the mining device the valves of cylinders with compressed air which fills lifting vessels, are actuated, the trawl takes off from the mining device and, having reached positive buoyancy, emerge to the surface where it is taken by the transportation vessel. Meanwhile for simplification of search the emerging vessel is fitted with the signalling device which automatically actuates after reaching of water surface.

EFFECT: improvement of efficiency of trawl utilisation due to reduction of number of idle runs, increase of completeness of excavation of useful component and decrease of dependence of working time from weather conditions.
