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] Divide the same copper-molybdenum sulfide ore into four groups of equal quality, the first inspection group, the second inspection group, the first control group, and the second control group, for mineral processing. The mineral processing process includes 1 roughing and 3 times of sweeping , 1 time of molybdenum beneficiation, the reagents used in each beneficiation process include flotation regulators, collectors and foaming agents, except for flotation regulators, the four groups of minerals The same amount of collectors and foaming agents are used in the selection process. In different beneficiation stages, the four groups of minerals use the same flotation adjustment agent respectively. The method of use is to first mix the minerals with the foaming agent, The collectors were mixed, and then the flotation regulator was added to carry out flotation; the flotation regulator used in the first investigation group was a mixture of sodium sulfide and drinking water, where...

Embodiment 2

[0036] The same copper-molybdenum sulfide ore as in Example 1 is used as a raw material, and the beneficiation process of 1 roughing, 3 sweeps, and 1 molybdenum beneficiation is also adopted. collector and foaming agent, the collector and foaming agent used and their consumption are all the same as in Example 1, the ore dressing method is to mix minerals with foaming agent and collector first, then add flotation to adjust Agent, the flotation regulator is the 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 sweeping 5~7wt%, the concentration of sodium sulfide in the flotation regulator used in the selection is 5~8wt%, the amount of the flotation regulator is 15g of the corresponding flotation regulator per kilogram of minerals; through the above process After beneficiation, the grade of the final concentrat...

Embodiment 3

[0038]The same copper-molybdenum sulfide ore as in Example 1 is used as a raw material, and the beneficiation process of 1 roughing, 3 sweeps, and 1 molybdenum beneficiation is also adopted. collector and foaming agent, the collector and foaming agent used and their consumption are all the same as in Example 1, the ore dressing method is to mix minerals with foaming agent and collector first, and then add the Flotation adjuster, the flotation adjuster is a mixture of sodium sulfide and drinking water, the concentration of sodium sulfide in the flotation adjuster used in roughing is 8~10wt%, and the concentration of sodium sulfide in the flotation adjuster used in sweeping is The concentration of sodium is 5~7wt%, and the concentration of sodium sulfide in the flotation regulator used in the beneficiation is 5~8wt%, and the flotation regulator used in the rough selection is under the voltage of 1.2~1.6V before use. Power on for 0.5~1h. The flotation regulator used in sweeping s...

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...
