PLANT FOR EXTRACTING IRON-MANGANESE BURS FROM OCEAN BOTTOM Russian patent published in 2006 - IPC E21C50/00 

FIELD: sea mining industry, possible use for extracting fields of hard mineral resources located on the surface of ocean bottom, primarily iron-manganese burs represented mainly by horizontal or slightly inclined beds.

SUBSTANCE: plant for extracting iron-manganese burs from ocean bottom contains carrying watercraft, which carries tools for controlling the plant and mounting-technological equipment, bottom device for collecting iron-manganese burs, mounted on frame, device for running iron-manganese bur slurry with pumps, device for lifting iron-manganese burs up to surface of ocean, made in form of transporter connected to carrying watercraft. Watercraft is made in form of self-propelled floating platform. Transporter is mounted on frame and can be engaged with flexible mesh vessels. Bottom device for collecting iron-manganese burs is connected to self-propelled floating platform by means of tow chain and is made in form of transporter-driven track chassis and device for running slurry of iron-manganese burs by multi-sectional piston pumps for feeding slurry from ocean bottom into mesh vessels of transporter by means of loading-transit pipe.

EFFECT: development of reliable plant for extracting iron-manganese burs from ocean bottom, providing for highly productive extraction of iron-manganese burs under conditions of industrial extraction of iron-manganese burs.
