What Is a Coagulator?

Coagulant (coagulant), also known as coagulant and coagulant, can make sol coagulate. It is mainly electrolytes such as salts, whose ions can neutralize the opposite charge of colloidal particles and cause coagulation. It is a substance used to clarify muddy water and purify sewage. For example, aluminum sulfate and alum are commonly used agglutinating agents. After adding to ice, it reacts chemically. After stirring, it forms flocs to promote the precipitation of suspended impurities. effect.

In the latex industry, it can be divided into: (1) strong coagulant, coagulation

In the beneficiation process, it is not easy to use fine flotation or other beneficiation methods to separate fine-grained minerals, but some minerals can be coagulated by adding coagulants to achieve the purpose of effective separation. Different minerals have different z-potentials on their surfaces. Particles with the same charge repel each other and are in a dispersed state and are not easy to coagulate. Particles with different charges are attracted to each other to neutralize the electrical property, and then coagulate. The main role of the coagulant is to change the electrical properties and interaction forces between the suspended particles in the pulp, reduce the collision of the same charged particles, or lose the charge on the particle surface, thereby coagulating and precipitating the fine-grained minerals.
In the beneficiation process, inorganic compounds (including inorganic macromolecules) are used as coagulants for fine-grained mineral agglomeration. Common coagulants are: basic aluminum chloride, ferric sulfate, polymeric ferric sulfate, ferrous sulfate, ferric chloride, zinc chloride, titanium tetrachloride, sulfuric acid, hydrochloric acid, carbon dioxide, sodium carbonate, lime, active dioxide Silicon and bentonite. The coagulant can be used to separate iron and clay minerals through coagulation. Lime is used as a coagulant to add to the concentrate pool to coagulate the concentrate and improve the efficiency of concentration and filtration.
The coagulant also has important uses in environmental protection, soil science and other aspects. For example, alum is used to purify drinking water, industrial water or factory wastewater, so that suspended particles contained in the water are condensed. It is also used for the coagulation of solid powders, such as dust control.
