In the process of selection, the enrichment process of the mineral is called flotation by using the mineral natural hydrophobic difference. In the flotation operation for grinding various fine ore mineral separation effectively, must be treated with drugs, and stir in pulp, inflatable, easy to adhesion and bubbles mineral with air bubbles floating, not with bubble adhesion of mineral in pulp, achieve the goal of mineral enrichment. A variety of potions used in flotation processes are called flotation agents, which are called adjutants in the flotation agents except for the agent and the foaming agent. The role of the adjuant is to adjust the function of the catcher and mineral to promote or inhibit the buoyancy of the mineral. Adjust the acidity of the pulp and the composition of ions. According to the effect of adjustment agent, it can be divided into pH modulator, activator, inhibitor, dispersant, flocculant etc. What are the dispersants in the mineral dressing agent?
Dispersants must be added in order for the ore to be dispersed. Commonly used dispersant have soda, sodium silicate, tripolyphosphate, tannin, lignin sulfonate etc. The common features of dispersion effect is that the electronegativity of ore grain surface, increase the repulsive force between particles, and make the particles surface presents strong hydrophilicity, prevent ore grain coalescence. It is necessary to increase the pH value of the pulp by increasing the pH value of the slurry before adding the dispersant when it is needed to disperse the slurry, and it is highly dispersible in the medium of strong alkali.
In the flotation operation, is the most commonly used dispersant sodium silicate, sodium silicate on the slime has dispersion effect, to improve the concentrate grade of valuable metals have obvious effect. Under the condition of the same kind of reagents in different flotation, tend to have different functions, sodium silicate has dispersed effect to slime dispersing agent, has inhibitory effect on quartz is inhibitors, also can adjust the pH value of slurry, is a regulator. So the classification of potions has its flexibility, as far as water glass is concerned, both as a dispersant and as an inhibitor.
Flotation processes are added to the pulp to improve and regulate the buoyancy of minerals. To make a lot of minerals without natural buoyancy, after the effect of flotation agents, they cannot be made to float, or otherwise. To artificially control the buoyancy of minerals. So some people say that flotation drugs are the backbone of flotation technology, and that makes sense. The development of flotation reagents and flotation technology's development is inseparable, flotation of production practice, promoted the research of flotation reagents, and the development of flotation reagents and promoted the development of flotation technology.
