Problems solved by technology

However, today's human research on seabed polymetallic sulfides is mainly limited to scientific discussions on deep-sea exploration, resource delineation, resource types, and types of valuable elements worldwide, and research on deep-sea mining is also limited to sample-level mining.
There are no reports about its process mineralogy, mineral processing and metallurgical extraction process.

Embodiment 1

[0061] Such as figure 1 As shown, a method for extracting valuable metals from seabed polymetallic sulfide ore coupled composite ore, comprising the following steps:

[0062] (1) Catalytic oxidative leaching: dry the seabed polymetallic sulfide ore coupling compound ore, then crush and ball mill to obtain -100 mesh composite mineral powder, place the composite mineral powder in the reaction vessel, add leaching agent, Catalysts and oxidants carry out the catalytic oxidation leaching reaction of materials, so that valuable elements such as copper and zinc in the composite ore are leached efficiently and enter the leach solution; sulfur, gold and silver in the composite ore enter the leaching residue, thereby being enriched. Specifically, first add 400ml [H + ] concentration is 4.5mol L -1 sulfuric acid solution; then, add -100 mesh 100g composite ore into the reactor, and add 3g of copper sulfate as a catalyst to the reactor at the same time, set the leaching temperature to ...

[0067] Such as figure 1 As shown, a method for extracting valuable metals from seabed polymetallic sulfide ore coupled composite ore, comprising the following steps:

[0068] (1) Catalytic oxidative leaching: dry the seabed polymetallic sulfide ore coupling compound ore, then crush and ball mill to obtain -100 mesh composite mineral powder, place the composite mineral powder in the reaction vessel, add leaching agent, Catalysts and oxidants carry out the catalytic oxidation leaching reaction of materials, so that valuable elements such as copper and zinc in the composite ore are leached efficiently and enter the leach solution; sulfur, gold and silver in the composite ore enter the leaching residue, thereby being enriched. Specifically, first add 500ml [H + ] concentration is 5.0mol L -1 Then, add -100 mesh 100g composite ore into the reactor, and add 5g of copper sulfate as a catalyst into the reactor at the same time, set the leaching temperature to 90°C, turn on the leac...

Embodiment 3

[0073] Such as figure 1 As shown, a method for extracting valuable metals from seabed polymetallic sulfide ore coupled composite ore, comprising the following steps:

[0074] (1) Catalytic oxidative leaching: dry the seabed polymetallic sulfide ore coupling composite ore, then crush and ball mill to obtain -100 mesh composite mineral powder, place the composite mineral powder in a reaction vessel, and add a leaching agent into the reaction vessel , Catalyst and oxidant to carry out the catalytic oxidation leaching reaction of the material, so that the valuable elements such as copper and zinc in the composite ore can be leached efficiently and enter the leachate; the sulfur, gold and silver in the composite ore enter the leaching slag to be enriched. Specifically, first add 300ml [H + ] concentration is 4.5mol L -1 Then, add -100 mesh 100g composite ore into the reactor, and add 8g of copper sulfate as a catalyst into the reactor at the same time, set the leaching temperatu...

Abstract

The invention discloses a method for extracting valuable metal from seabed multi-metal sulfide mineral coupling complex ore. The method comprises the steps of obtaining leaching liquid containing copper and zinc and leaching slag containing sulfur, gold and silver through catalysis, oxidation and leaching; exacting copper products and zinc products out of the leaching liquid, and exacting sulfur products, gold products and silver products out of the leaching slag. By means of the method, valuable elements including copper, zinc, gold, silver and sulfur in the seabed multi-metal sulfide mineral coupling complex ore can be recycled comprehensively, the method has the advantages that the multipurpose utilization rate is high, the recycling rate is high, the process is simple, the cleanliness is achieved, and energy is saved, and the method is effective in processing new resources in the seabed multi-metal sulfide mineral coupling complex ore.

Description

technical field [0001] The invention relates to the technical field of hydrometallurgy, in particular to a method for extracting valuable metals from a multimetallic sulfide ore coupled compound ore on the seabed, and realizes the comprehensive recovery of copper, zinc, sulfur and gold in the compound ore coupled with polymetallic sulfide ore on the seabed ,silver. Background technique [0002] Non-ferrous metals are indispensable and important substances in modern industry. After decades of mining, the reserves of valuable metals on land have been greatly reduced and are becoming increasingly depleted. Therefore, it is necessary to actively seek and develop new non-ferrous metal mineral resources. From the perspective of resource development strategy, the development of seabed mineral resources is of great significance. [0003] Since the first discovery of black chimneys and their accumulated sulfides on the eastern Pacific Ocean Ridge in 1978, submarine hydrothermal acti...
