2. Foam flotation: A method in which fine particles are sorted based on the difference in physicochemical properties of mineral surfaces using foam as a carrier.
3. Optional: The difficulty of mineral flotation.
4. Grade: The percentage of the target in the ore.
5. Concentrate yield: The percentage of mineral flotation concentrate products in the ore.
6. Wetting: Wetting is a common phenomenon in nature due to the interfacial action produced by the displacement of liquid solid surfaces on solid surfaces.
7. Three-phase wetting periphery: When the bubble adheres to the surface of the mineral immersed in water, when the wetting balance is reached, the bubble forms a periphery surrounded by three-phase contact points on the surface of the mineral.
8. Wetting contact angle: The tangential line of the gas-liquid interface at any point P on the periphery of the three-phase wetting, and the angle formed by the liquid phase formed between the solid-liquid interface.
9. Wetting block: During the wetting process, the wetting periphery is unfolded or the movement is hindered, and the equilibrium contact angle is changed. This phenomenon is called wetting block.
10. Hydration: Water molecules are aligned on the mineral surface (or ionic surface).
11. Hydrophobic mineral surface: a hydrophobic surface with poor wettability and large contact angle.
12. Hydrophilic mineral surface: a hydrophilic surface with good wettability and small contact angle.
13. Hydrophobic mineral: mineral with weak polar surface, small attraction to water molecules, and weak hydration.
14. Adhesive work: The change of the free energy of the system before and after attachment when the ore particles and the bubbles adhere to only a unit area.
15. Positioning ions: ions adsorbed in the inner layer of the electric double layer.
16. Balance ion: After the surface of the particle is charged, the counter ion in the solution is attracted, that is, the counter ion adsorbed by the outer layer of the electric double layer.
17. Total potential: refers to the potential difference between the mineral surface and the solution. Also called surface potential.
18. Stern Potential: The potential difference between the Stern layer and the solution.
19. Dynamic potential: The potential on the sliding surface and the potential difference inside the solution, also called Zate potential.
20. Zero point: The negative logarithm of the positional ion in the solution when the static charge on the mineral surface is zero.
21. Isoelectric point: The negative logarithm of the positional ion in the solution when the motorized potential on the mineral surface is zero.
22. Positive adsorption: The concentration of the solute in the surface layer after adsorption is greater than the concentration inside the solution. This adsorption is called positive adsorption.
23. Negative adsorption: The concentration of the solute in the surface layer after adsorption is less than the concentration inside the solution. This adsorption is called negative adsorption.
24. Physical adsorption: adsorption caused by intermolecular forces.
25. Characteristic adsorption: adsorption in addition to electrostatic adsorption in the adsorption of electric double layer. Has a special affinity for a certain component of the solution.
26. Semi-micelle adsorption: Under the action of van der Waals force, the non-polar end of the mineral surface adsorption collector collides to form a micelle-like structure.
27. Collector: It acts on the solid-liquid interface and is selective to increase the hydrophobicity of the solid surface, increase the floatability, promote the adhesion of bubbles, and enhance the adhesion of the solid flotation agent.
28. Foaming agent: a surfactant that acts on the gas-liquid interface to reduce surface tension and has a foaming effect.
29. Three-phase foam: a foam composed of liquid, gas, and solid three phases.
30. Two-phase foam: a foam composed of two phases of liquid and gas.
31. Inhibition: destroys and weakens the adsorption of minerals on the collector, enhances the hydrophilicity of the mineral surface, and thus reduces the floatability of the mineral.
32. Activation: It promotes and enhances the interaction of minerals with collectors and improves the floatability of minerals.
33. Bubble mineralization: The phenomenon in which particles adhere to bubbles during flotation.
34. Mineralized bubbles: bubbles attached to the ore particles.
35. Flotation kinetics: The quantitative relationship of foam products as a function of flotation time.
36. Flotation speed constant: Flotation speed at a concentration of 1. Is a proportional constant.
37. Contact time: The time elapsed from the moment of collision to the moment of falling off.
38. Induction time: The time elapsed from the moment of collision to the moment of attachment.
39. Contact curve: The relationship between the amount of the same mineral and the same agent, whether the bubble can be attached to the mineral and the pH value is called the contact curve.
40. Aeration amount: The quantity of gas that can be inhaled per unit time and unit flotation tank area when the flotation machine works normally.
41. Pulp pass capacity: The number of cubic meters of pulp that can be processed per unit time of the flotation machine.
42. Inflatable uniformity: the uniformity of the distribution of bubbles in the slurry.
43. Number of flotation segments: The number of times the flotation is combined with flotation.
44. Flotation cycle: loop, after a flotation, a product is called a cycle.
45. Flotation process: When the ore is flotation, the slurry flows through the general name of each operation.
46. ​​Secondary enrichment: the upper layer of bubbles in the foam layer is broken and the mechanically entrained water forms a effluent stream, which is returned to the slurry with the non-objectives entrained by the effluent stream. This enrichment in the foam layer is called For secondary enrichment.
47. Selected operations: Sorting the concentrates for roughing operations.
48. Sweeping: A sorting operation for tailings for rough selection (or sweeping or pre-flotation) operations.
49. Roughing operation: The first sorting operation of the slurry in the flotation process.
