Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] Such as figure 1 , figure 2 As shown, a deep-sea mining floating platform is mainly used for collecting and beneficiating seabed raw ore sand. The deep-sea mining floating platform includes a hull 1 floating on the sea surface, and a raw ore bin 11 and tailings are separately arranged in the lower part of the hull The warehouse 12 is similar to the existing mining ship. The raw ore sand on the seabed is extracted by a high-power sand pump 2. The sand pump is powered by a diesel engine. The sand suction port of the sand pump is connected to the seabed through a pipeline. The sand outlet of the sand pump is connected to the raw ore bin through a pipeline, so that the raw ore sand is extracted into the raw ore bin.
[0039] Different from the prior art, the present invention is directly provided with a magnetic separator 3 for mineral se...

The invention discloses a deep sea mining method and a deep sea mining apparatus. According to the present invention, mining and ore dressing are integrated, wherein raw ore on the seabed is sucked into the raw mine bin of a ship by a sand sucking pump on the ship, impurities are separated with a vibrating sieve mesh, fine ore is selected with a magnetic separator and is directly conveyed to a transport ship through a screw conveyor and a belt conveyor, and the tailing is transported to the seabed away from the mining area through a tailing pump and is subjected to in-situ backfill; and the tailing treatment is simple, no adverse effect is caused on the environment, a lot of transporting capacity can be saved so as to reduce the mining cost, and the magnetic separator adopts the long strip structure, such that the raw ore can be subjected to complete and accurate ore dressing so as to effectively avoid the waste of resources.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a mining method for collecting iron-containing raw ore sand in deep sea and a corresponding deep sea mining device. Background technique [0002] With the dwindling of land mineral resources, people began to turn their attention to the sea, which is rich in mineral resources. In some areas, people found a large number of coastal placer, mainly titanium-containing magnetite. At present, the usual mining method It uses an offshore mining platform or a mining ship to pump the ore from the seabed to the mining platform or mining ship, and then uses the corresponding slurry pump to transport the collected raw ore to the transshipment transport ship. The transport ship will The raw ore is transported to the onshore concentrator for beneficiation to form concentrated ore that can be used for smelting. For example, a kind of " deep-sea collecting and distributing mining system " disclose...
