What should I do if I encounter foam problems in beneficiation and mining?

Customer type

1. Customer information: Thailand beneficiation and mining defoamer, Thailand Xu engineer in charge of mining. Previously, due to the problem of defoamer, the mining process was always unsatisfactory, so I found Nanhui manufacturer.

2. Sample information: beneficiation agent

3. Customer requirements: To solve the problem of beneficiation and defoaming, it must have the advantages of alkali resistance, pressure resistance, temperature resistance, safety, non-toxicity, and stable performance.

Principle and analysis of defoaming

1. Analysis of the cause of blistering:

In the beneficiation process of non-ferrous metals such as gold, silver, copper, tin and ferrous metals such as iron with high sulfur ores, flotation methods are more frequently used. Flotation is a technical method to separate useful minerals from ore according to the different physical and chemical properties of the surface of mineral particles. Flotation is the process of separating mineral particles by using the difference in physical and chemical properties of mineral surfaces. It is the most widely used method of beneficiation. It is suitable for processing fine and fine-grained materials. It is difficult to recover fine ore particles smaller than 10μm with other beneficiation methods. It can also be processed by flotation. The ore is crushed, coarsely ground, finely ground, finely ground and other processes to form fine ore powder. In the ore slurry pool, different beneficiation agents such as xanthate, black medicine or ethyl sulfur nitrogen are added as metal capture agents. The foaming agent makes the mineral slurry float, or simply inflate the mineral slurry directly to make the mineral powder float to screen various metal components, so as to achieve the purpose of selecting different metals.

2. The hazards of blistering:

Flotation is a cyclic process, and the control of pulp foam is closely related to the flotation efficiency. Excessively large foam and too small foam will seriously affect the beneficiation efficiency and reduce the extraction rate. Therefore, there are very high requirements for the selection and addition of defoamers.

3. Analysis of the program of fully synthetic cutting fluid defoamer

According to different metal slurries, what kind of metal trapping agent and foaming agent are used, select the corresponding defoaming agent. It is best to test the addition amount by adding the defoaming agent in a cycle in the concentrator. The laboratory data can be used as a preliminary test. result. The general addition amount ranges from one hundred thousandth to one million units.

Solution to cutting fluid foaming

Nanhui beneficiation defoamer solves the problem of beneficiation defoaming. There are many foaming substances in ore beneficiation. In the beneficiation, the foaming ability of the foam is enhanced. This defoamer is a special defoamer specially designed for mining and beneficiation. It is suitable for defoaming and defoaming of different systems. It has strong alkali resistance, pressure resistance and temperature resistance. This product is water-soluble emulsification It has the advantages of low dosage, safe and non-toxic, stable performance and so on.
