Summary of the Mineral Processing Agent Exhibition

The 4th National Exchange Conference on the Application of New Mining Reagents and New Technologies was held in Xi'an last year. The conference introduced the development status and practical application of mineral processing reagents, as well as the research and development results of new reagents, through special reports, exhibitions, on-site technical exchanges, etc., to build a cooperative platform for supply, procurement and display of new mining reagents, promote and apply the research and development results of new environmentally friendly mining reagents, and help mining companies develop high-quality.

The organizer said that the construction of green mines must first ensure the full utilization of resources. For mining companies, it is particularly important to improve the comprehensive recycling efficiency of resources and the quality of mineral processing production, and strengthen the application of new technologies and new reagents, which is directly related to the comprehensive utilization level of resources of mining companies, economic benefits and future development. For pharmaceutical companies, it is necessary to think deeply about how to take into account the leading production and research and development, the high quality of product quality, the expansion of market customers, and the construction of brands, and produce more green and environmentally friendly "panaceas". This is not only the expectation of mining companies, but also a new requirement of the new era.

The organizer made a special report entitled "Scientific Application of Mineral Processing Reagent Production Site" at the exchange meeting. Starting from the production practice of mineral processing reagents, the scientific application of mineral processing reagent production site was discussed in detail, which brought inspiration to reagent manufacturers and mining enterprises.

According to reports, many mineral processing reagents are replaceable and substitutable, especially special-effect reagents and environmentally friendly reagents, which have huge application potential in the future and deserve more experts to invest in research and development. The current production and manufacturing of mineral processing reagents is unstable due to the difference in the quality of reagents from different batches of the same reagent manufacturer. Therefore, it is necessary to strengthen the refined production of mineral processing reagents. To ensure the stability of reagent quality, it is crucial to optimize the design of the reagent table. The mineral processing reagent table is equivalent to the engine of the mineral processing plant, but some mineral processing plants do not pay enough attention to the design of the reagent table. The most intuitive thing is the hygiene level of the mineral processing reagent table, which also reflects the management level of the mineral processing plant from one aspect.

He also proposed that the design of the ore dressing agent table should follow the principle of "convenient preparation and measurement, stable and accurate addition of all agent addition points without blockage, and smooth operation". The agent dosage engineer should clearly know the amount of agent used per ton of ore, and the workers should also know the amount of agent consumed per minute in ore dressing.

"The location of the agent addition is also one of the important factors affecting production indicators." Some agents need to extend the stirring time. Dispersed addition is better than centralized addition. The proportion of addition is generally 50% less than the previous one. Each section of the selection should have an inhibitor addition point, which can be added in an emergency when the product is unqualified. Each type of ore has an optimal agent type, and the agent type must be determined through ore dressing tests.

The quality of the agent is another important factor affecting the ore dressing indicators. Most of the differences in the quality of agents are due to different contents of active ingredients. When selecting agents, the dosage of the same agent from different manufacturers should be compared to determine the best agent through experiments. Each type of ore has an optimal dosage of reagents, which must also be determined through mineral processing tests. Even if the right reagents are selected, different dosages will directly affect the mineral processing indicators. The same reagent has different dosages with different qualities. Each concentrator should master the precise dosage of reagents, find out the influence of reagents on indicators, and even the corresponding mineral processing results of the increase or decrease of each reagent dosage. Therefore, it is necessary to conduct spot checks on the dosage of reagents on time to ensure the accuracy of the dosage of reagents. In addition, the return water of most concentrators can be utilized, which has little impact on production indicators. Many concentrators did not conduct return water utilization tests, but attributed the reasons for poor indicators to return water. Reasonable use of return water can greatly reduce the consumption of reagents and reduce pollution. For environmental protection and cost considerations, return water must be used.

During the exchange meeting, the procurement demand for mining reagents was also released on site, and key project negotiations, expert on-site technical guidance, visits and inspections and other activities were carried out.
