Problems solved by technology

[0005] The purpose of the present invention is to solve a technical problem that is the difficulty of separating copper, zinc and sulfur in the existing deep-sea high-sulfur copper-zinc ore and the problem of a large amount of loss of chemicals. The adsorption relationship of different sulfide minerals on the surface of different sulfide minerals and the influence of defoamers on the flotation environment can realize the selective collection of copper minerals, the effective separation of copper, zinc and sulfur, and greatly improve the recovery rate.

Embodiment 1

[0026]Embodiment 1: A method for flotation separation of copper, zinc and sulfur from deep-sea high-sulfur copper-zinc ore, which includes the following steps: (1) raw ore dehydration: filter and dehydrate the raw ore slurry, remove part of the seabed oxidation and then dilute Acidic water and interfering ions formed; (2) Grinding: add sodium sulfide 800g / t to the mill, and grind the dehydrated pulp to -0.074mm, accounting for 93.7%, to obtain a finely ground pulp; (3) Stage 1 Floatable flotation: add zinc sulfate 7000g / t, sodium sulfite 3000g / t and composite collector 120g / t to the pulverized ore pulp in turn to make slurry, and then carry out first-class flotation flotation after slurry mixing to obtain copper Zinc-sulfur mixed coarse concentrate and zinc-sulfur mixed tailings 1; (4) Stage 2 flotation: add zinc sulfate 2000 / t, sodium sulfite 1000g / t and composite collection to the copper-zinc-sulfur mixed coarse concentrate in sequence 20g / t, and after pulping, carry out sec...

Abstract

The invention discloses a method for flotation separation of copper, zinc and sulfur from deep-sea high-sulfur copper-zinc ore, comprising the following steps: (1) dehydration of raw ore; (2) grinding; (3) first-class flotation (4) Phase II flotation flotation; (5) Zinc and sulfur separation and roughing; (6) Zinc rough concentrate concentration; (7) Sulfur rough concentrate concentration. The present invention aims at high-grade copper-zinc-sulfur ores, especially deep-sea high-sulfur copper-zinc ores, and can realize effective separation by adopting conventional inhibitors. The invention solves the problem that the currently commonly used copper-zinc-sulfur separation flotation process is too long, can effectively reduce the process flow, improve work efficiency, and reduce costs. The composite collector used at the same time has little environmental pollution, the method is simple and easy, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the mineral processing field of copper-zinc sulfide ore, in particular to a method for flotation separation of copper, zinc and sulfur from deep-sea high-sulfur copper-zinc ore. 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 subsequent sorting, utilization, development and research of deep-sea polymetallic sulphide resources are still in their infancy. How to efficiently sort and recover seabed mineral resources has become imminent. [0003] The separation of copper and zinc is a problem that has plagued the industry for a ...
