Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the pH value of deep-sea high-sulfur and high-copper ores is extremely low, and the ions contained in seawater not only seriously affect the formation of flotation foam, but also consume a large amount of flotation reagents, so that the production of copper minerals and sulfur minerals cannot be guaranteed. effective recovery and separation of

Embodiment 2

[0029] Embodiment 2: the method for reclaiming copper and sulfur from seabed high-sulfur and high-copper ore, it comprises the following steps: (1), raw ore is ground and filtered dehydration: the raw ore pulp after fully dissociated is carried out filtration dehydration, makes part in The moisture inside the material seeps out after convective diffusion, and the acidic water with pH=4.8 and the copper selection operation feedstock with a concentration of 72% are obtained, in which the acidic water is reserved for the concentrated underflow pulping dilution of the sulfur selection operation; (2), Dilution and roughing of feedstock for copper beneficiation: dilute and stir the 72% feedstock for copper beneficiation with neutral water, adjust the pulp concentration to 28%, add quicklime 10kg / t, and stir for 3 minutes, the measured pH=12.3, Then add TY-1 reagent 700g / t and 43# reagent 120g / t, stir for 2min, and float for 9min to obtain copper roughing foam and copper roughing tail...

Embodiment 3

[0031] Embodiment 3: the method for reclaiming copper and sulfur from seabed high-sulfur and high-copper ore, it comprises the following steps: (1), raw ore is ground and filtered dehydration: the raw ore pulp after fully dissociated is carried out filtration dehydration, makes part in The moisture inside the material seeps out after convective diffusion, and acidic water with pH=5.5 and 75% concentration of copper selection operation feed are obtained, in which the acidic water is reserved for the concentrated underflow pulping dilution of sulfur selection operation; (2), Dilution and roughing of feedstock for copper beneficiation: dilute and stir the 75% copper beneficiation feedstock with neutral water, adjust the slurry concentration to 30%, add quicklime 10kg / t, and stir for 4min, the measured pH=12.2, Then add 700g / t of TY-1 reagent and 120g / t of 43# reagent, stir for 3 minutes, and float for 10 minutes to obtain copper roughing foam and copper roughing tailings; Copper ...

Abstract

The invention discloses a method for comprehensively recovering copper and sulfur from deep-sea high-sulfur and high-copper ores and its application, which includes the following steps: (1) filtering and dehydrating raw ore after grinding; 3) Triple sweeping of copper roughing tailings; (4) Copper roughing + copper sweeping foam combined concentration; (5) Copper beneficiation foam secondary concentration; (6) Concentration and dehydration of copper sweeping tailings; ( 7) Sulfur concentration and underflow pulping roughing; (8) Sulfur roughing tailings sweeping; (9) Sulfur roughing + sulfur sweeping foam concentration. The beneficial effect of the present invention is that through filtration dehydration and concentration dehydration successively, the acidic water and high-alkaline tailings water that are separated out are respectively carried out in the way of "transferring flowers and trees" to separate sulfur and copper, which solves the problem of high-sulfur and high-copper mines in the deep sea. The use of traditional reagents in stone cannot effectively adjust the pH value, the use of traditional processes cannot avoid the interference of seawater ions on flotation operations, and it is impossible to ensure the effective separation and recovery of copper minerals and sulfur minerals and other technical problems.

Description

technical field [0001] The invention relates to the technical field of mineral processing engineering of copper sulfide ore, in particular to a method for comprehensively recovering sulfur and copper from deep-sea high-sulfur and high-copper ore and its application. Background technique [0002] With the continuous increase of human demand for mineral resources and the decrease of terrestrial mineral resources, deep sea mineral resources have received more and more attention. Especially for deep-sea deposits with large reserves, high grade and easy mining, they are the first choice in the "enclosure" campaign of various countries. Although major breakthroughs have been made in seabed mining technology in China, the research on the subsequent separation and utilization of deep-sea polymetallic sulphide resources is still in its infancy, so how to efficiently sort and recover seabed mineral resources has become imminent. [0003] The magma ejected from the crater, mixed with ...
