Problems solved by technology

[0004] In some technologies, in order to reduce the complexity of the flotation regulator, only one or two or three substances are selected as the flotation regulator, but at the same time it is necessary to increase its dosage, resulting in an increase in production costs

Embodiment 1

[0031] The same copper-molybdenum sulfide ore is divided into four groups of equal quality: the first investigation group, the second investigation group, the first control group, and the second control group for beneficiation. The beneficiation process includes 1 roughing and 3 sweeping. , One time molybdenum beneficiation, the reagents used in each beneficiation process include flotation regulators, collectors and foaming agents. In addition to flotation regulators, four groups of minerals are In the selection process, the same collector and foaming agent are used in the same amount. In different beneficiation stages, the four groups of minerals each use the same constant flotation regulator. The method of use is to first combine the minerals with the foaming agent, The collector was mixed, and then the flotation regulator was added for flotation; the flotation regulator used by the first investigation group was a mixture of sodium sulfide and drinking water, and the concentra...

Embodiment 2

[0036] The same copper-molybdenum sulfide ore as in Example 1 is used as the raw material, and the beneficiation process of 1 roughing, 3 sweeping, and 1 molybdenum beneficiation is also adopted. The reagents used for each beneficiation include flotation regulators and traps. Collector and foaming agent, the used collector and foaming agent and their dosage are the same as in Example 1. The beneficiation method is to first mix the mineral with foaming agent and collector, and then add flotation adjustment The flotation regulator is a mixture of sodium sulfide and drinking water. The concentration of sodium sulfide in the flotation regulator used in rough selection is 8~10wt%, and the concentration of sodium sulfide in the flotation regulator used in sweep selection 5~7wt%, the concentration of sodium sulfide in the flotation regulator used in the beneficiation is 5~8wt%, and the amount of flotation regulator is 15g per kilogram of mineral; after the above process After benefici...

Embodiment 3

[0038] The same copper-molybdenum sulfide ore as in Example 1 is used as the raw material, and the beneficiation process of 1 roughing, 3 sweeping, and 1 molybdenum beneficiation is also adopted. Collector and foaming agent, the used collector and foaming agent and their amounts are the same as in Example 1. The beneficiation method is to first mix the mineral with foaming agent and collector, and then add the electrified Flotation regulator. The flotation regulator is a mixture of sodium sulfide and drinking water. The concentration of sodium sulfide in the flotation regulator used in rough selection is 8-10wt%, and it is vulcanized in the flotation regulator used in sweeping The concentration of sodium is 5~7wt%, and the concentration of sodium sulfide in the flotation regulator used in the beneficiation is 5~8wt%. The flotation regulator used in the rough selection should be at a voltage of 1.2~1.6V before use Power on for 0.5~1h, the flotation regulator used for scanning sh...

Abstract

The invention discloses a flotation regulator applied to copper-molybdenum sulphide ore separating flotation and an application method thereof. The flotation regulator is a mixed solution obtained by dissolving sodium sulphide in domestic drinking water. The flotation regulator can effectively improve the grade of concentrates obtained after flotation, meanwhile, has high flotation efficiency, and can greatly reduce the usage amount of sodium sulphide.

Description

Technical field [0001] The invention relates to the technical field of beneficiation, in particular to the technical field of copper-molybdenum separation flotation. Background technique [0002] In the process of beneficiation, the different physical and chemical properties of different minerals are used. The enrichment process of flotating different types of minerals from the grinding and grading overflow slurry is called flotation. In the flotation operation, it is used to make the ore finely ground. The various minerals can be effectively separated, usually must be treated with chemicals, so that part of the minerals will float up after the treatment, while leaving other minerals in the slurry, thereby achieving the process of separation and enrichment. It is difficult for a single flotation to achieve a complete separation effect. Therefore, in actual production, the separation of minerals usually goes through multiple processes such as rough selection, sweep selection, and ...
