Basic understanding of mining inhibitors

According to a large amount of experimental data, the summary inhibition mechanism is:

1. The first inhibition mechanism is: due to the physical adsorption, chemical adsorption or chemical attachment of the modifier or colloidal ions in certain microdomains of the mineral surface, the hydration of these adsorbed colloidal particles or ions leads to the formation of a firm run. Wet film.

2. The second inhibition mechanism is that the attachment of the regulator ion is not only due to the fact that it excludes other ions, but also because it occupies the micro-region of the solid surface to which the collector ions can adhere, closing the collector. Attachment center.

3. The third inhibition mechanism is: deactivation, which eliminates the activity of the solid surface on the collector by dissolution or chemical changes in the active center attached to the collector.

4. The fourth inhibition mechanism is that the active site of the collector attachment on the mineral surface is reduced by the combination of the conditioning agent and the activated ions in the solution to form a stable complex or insoluble compound.

5. The fifth inhibition mechanism is that the regulator ion and the collector ion combine in an aqueous medium to form a low activity, usually poorly soluble compound.

6. The sixth inhibition mechanism is related to the change of the surface state of the bubble. Under certain conditions, the surface of the cheongsam is adsorbed with a dense film of colloidal compound, which is mostly a product of chemical reaction in the aqueous phase of the slurry, preventing the solid particles from adhering to the bubble. Causes suppression of flotation.

7. The seventh type is the adsorption of ions on the mineral surface that increase the amount of inhibitor adsorption.
