Addition of flotation reagent during flotation

Addition of flotation reagent during flotation process:

    1. The dosage of the added medicine can be determined by calculating the volume of the medicine solution flowing out per minute. In order to avoid changes in the dosage of the medicine, the dosage of the medicine must be checked frequently, at least once every 30 minutes. After the flotation reagent is configured in the dispensing room, it is sent to each oil tank in the reagent room. The medicine enters each drug delivery machine from the oil medicine tank along the catheter.

    2. The flotation agent of the flotation machine can be added in two ways: one-time dosing and segmented dosing. One-time dosing refers to adding a certain agent to the slurry before flotation, which can increase the initial speed of the flotation process. Although the later speed is reduced, the total flotation time is still short, which is beneficial to improve the flotation index. Generally, for medicaments that are easily soluble in water, will not be taken away by the foam machinery, and are not easy to react and fail in the slurry (such as xanthate, soda, lime), one dosing should be used. Segmented dosing refers to adding a certain agent in several batches during the flotation process. Generally, 60-70% of the total amount is added before flotation, and the remaining 30-40% is added to appropriate places in several batches. Such segmented dosing can improve the quality of the concentrate, but the entire flotation time is increased due to the decrease in the initial flotation speed.

    3. Dosing methods should also be determined according to the nature of the ore. For example, when the soluble salts in the slurry are relatively high and a large amount of medicament will be adsorbed, it is advantageous to adopt staged dosing. For another example, in some preferential flotation situations, it is often beneficial to add collectors in stages in order to reduce the negative effect of inhibitors on minerals to be floated. In the flotation process of the flotation machine, the choice and addition of reagents are particularly important. There are many kinds of agents commonly used, such as collectors, black medicines, foaming agents, etc. We generally pay more attention to the choice of agents in the beneficiation process, the amount of intake, and the time invested. Every step needs to be careful to ensure the normal flotation process.
