Example Embodiment

[0030] Example 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,...

Example Embodiment

[0035] Example 2

[0036] The same copper-molybdenum sulfide ore as in Example 1 was used as the raw material, and the beneficiation process of 1 roughing, 3 sweeping and 1 molybdenum beneficiation was also adopted. 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 beneficiation, the final grade of the concentrate obtained is tested, ...

Example Embodiment

[0037] Example 3

[0038] The same copper-molybdenum sulfide ore as in Example 1 was used as the raw material, and the beneficiation process of 1 roughing, 3 sweeping and 1 molybdenum beneficiation was 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 u...

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 ore dressing, in particular to the technical field of separation and flotation of copper and molybdenum. Background technique [0002] In the beneficiation process, using different physical and chemical properties of different minerals, the enrichment process of flotation to extract different types of minerals from the overflow slurry of grinding and classification is called flotation. The various minerals can be effectively separated, usually they must be treated with chemicals, so that some minerals will float after treatment, while other minerals will be left in the slurry, thus achieving the process of separation and enrichment. It is difficult to achieve a complete separation effect in a single flotation. Therefore, in actual production, the separation of minerals usually goes through multiple processes such as roughing, sweeping, and fine selection. These processes can all choose the flotation metho...
