Deep sea mining method and deep sea mining apparatus

Abstract

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 field of mining technology, in particular to a mining method for collecting iron-containing raw ore in the 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 ocean, which is rich in mineral resources. In some areas, people have discovered a large number of coastal placers, mainly titanium-containing magnetite. At present, the usual mining method It is through an offshore mining platform or a mining ship with a sand pump to pump the seabed ore to the mining platform or mining ship, and then use the corresponding slurry pump to transport the collected raw ore to the transport ship. The transport ship will The raw ore is transported to the concentrator on land for beneficiation to form a concentrate that can be used for smelting. For example, a "deep-sea distributed mining system" disclosed in Chinese patent do...

AI Technical Summary

Problems solved by technology

[0006] An object of the present invention is to solve the problems of large waste of transport capacity and troublesome tailings disposal in the existing deep-sea mining method, and provide a deep-sea mining method and device whose tailings processing is simple and will not cause adverse effects on the environment , and can save a lot of capacity to reduce mining costs

[0007] Another object of the present invention is to provide a method and device for deep sea mining, which can fully and accurately select raw ore sand in order to solve the problem of inaccurate mineral separation and easy resource waste in deep sea mining. , effectively avoiding the waste of resources
