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 application of the method. The method comprises the following steps: (1) grinding raw ores, and filtering and dehydrating the raw ores; (2) diluting and roughing the feed of the copper separation operation; (3) scavenging the copper roughing tailings for three times;(4) combining copper roughing with copper scavenging foam and finely selecting; (5) performing secondary selection of copper selection foam; (6) concentrating and dehydrating the copper scavenging tailings; (7) carrying out sulfur concentration, underflow size mixing and roughing; (8) scavenging sulfur roughing tailings; and (9) performing sulfur roughing and sulfur scavenging foam concentration.The method has the beneficial effects that filtration dehydration and concentration dehydration are performed in sequence; acid water and high-alkali tailing water which are respectively removed arerespectively subjected to sulfur separation and copper separation in a grafting and transplanting manner; the technical problems that the pH value cannot be effectively adjusted by adopting a traditional agent in deep sea high-sulfur high-copper ore, interference of seawater ions on flotation operation cannot be avoided by adopting a traditional technological process, and effective separation andrecovery of copper ore and sulfur ore cannot be guaranteed are solved.

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 ...
