preparation example Construction

[0017] The present invention also provides a preparation method of sphalerite activator, the steps comprising: adding copper sulfate, lead nitrate, lauric acid, and an appropriate amount of water into a high-pressure reaction kettle according to the corresponding component ratios, Stir and react at 95°C to 100°C for 25 minutes, volatilize steam, cool to 60°C to 75°C, add sodium sulfide and oxidized paraffin soap and continue to stir and react for 40 minutes, cool to room temperature, and the obtained paste agent is sphalerite flotation activator.

[0018] As a preference, add copper sulfate, lead nitrate, lauric acid, and appropriate amount of water into the autoclave according to the corresponding proportions of each component, stir and react at 2 atmospheres at 100°C for 25 minutes, evaporate steam, and cool to 60°C , add sodium sulfide, oxidized paraffin soap and continue to stir and react for 40 minutes, cool to room temperature, and the obtained paste agent is sphalerite ...

Embodiment 1

[0025] According to the mass ratio of each raw material, copper sulfate 55%, lead nitrate 15%, sodium sulfide 10%, oxidized paraffin wax soap 10%, lauric acid 10%, copper sulfate, lead nitrate, lauric acid, water are added to the autoclave, in 2 Stir and react at 100°C for 25 minutes under atmospheric pressure, volatilize steam, cool to 60°C, add sodium sulfide and oxidized paraffin soap and continue to stir and react for 40 minutes, cool to room temperature, and the obtained paste agent is sphalerite flotation activator.

[0026] The activator prepared in this example was left to stand at room temperature for 48 hours, and it was observed that the activator did not separate, showing high stability.

[0027] The sphalerite flotation activator prepared in this example was tested for the flotation performance of sphalerite containing iron sulfide. Specifically, the sphalerite flotation activator prepared above was 400g / t, 60°C Hot water and sodium carbonate are mixed evenly at a...

Abstract

The invention relates to a marmatite flotation activating agent, a preparation method and application thereof, belonging to the field of mineral processing flotation reagents. The invention aims at solving the technical problems that the activation selectivity of the marmatite flotation activating agent is weak, thereby leading the existence of lots of minerals such as ferric sulfide in marmatiteand the low recovery rate of the marmatite. According to the technical scheme, the marmatite flotation activating agent is prepared by reaction of 52-56% of copper sulfate, 12-15% of lead nitrate, 10-13% of sodium sulfide, 8-11% of oxidized paraffin soap and 9-12% of lauric acid under high temperature and high pressure. The marmatite flotation activating agent has good stability and strong selectivity. Marmatite concentrate with the grade of 46.53%-49.54% and the recovery rate of 78%-83.34% is obtained by a three-rough one-sweeping two-refining floatation technology under the combined action of the marmatite flotation activating agent and other flotation reagents such as lime, sodium n-butylxanthate and oil NO.2 in the marmatite flotation process.

Description

technical field [0001] The invention belongs to the field of flotation agents for mineral processing, and in particular relates to a sphalerite flotation activator and a preparation method and application thereof. Background technique [0002] The flotation method is a beneficiation method that uses the difference in the physical and chemical properties of the mineral surface to separate the minerals. The froth flotation is widely used in industry. Under the action, the useful minerals selectively attach to the air bubbles in the pulp, and then float up to the surface of the pulp, and the gangue minerals settle to the bottom of the pulp to separate the useful minerals from the gangue. [0003] Sphalerite is a sulfide mineral whose main chemical composition is ZnS and whose crystals belong to the equiaxed crystal system. It usually contains iron, and the iron content can reach up to 30%. Those with iron content greater than 10% are called sphalerite. Contains rare elements s...
