Potassium Salt Resources are seriously scarce in China, far from meeting the growing China domestic demand, Potassium Salt Mine is listed as one of the urgent shortage of minerals by China. How to improve the production efficiency and product quality of potash, increase the utilization rate of potash resources, and maximize the benefits is a problem for potash producers all over the world, and the rapid and accurate detection of potassium content in the process of potash beneficiation is one of the problems.

The traditional potassium content testing needs to take samples from the mining field, then make samples in the laboratory, and finally analyze the samples by chemical method, the whole process takes several hours, and the test results are seriously delayed. Moreover, the sampling only uses a very small part of the material flow, which is not very representative.

DFMC independently developed neutron activation method solid phase potassium salt online analyzer, using the world's most advanced instantaneous gamma neutron activation analysis technology, with high sensitivity, non-destructive, suitable for large samples online analysis of the significant advantages, online real-time detection of potash of K⁺,Mg²⁺,SO₄^2-,Cl^-,Na⁺ etc.,it play a vital role in quality control and process optimization.

The product showed satisfactory static and dynamic adaptability in the practical application in Guotou Luo Potassium Company. In terms of static Root-Mean-Square, the Root-Mean-Square error of each element is within reasonable range, and the consistency between the assay value and the analyzer reaches the technical index expected by the test. In terms of dynamic adaptability, the trends of K⁺,Mg²⁺,SO₄^2-,Cl^-,Na⁺ etc. showed extremely high correlation. After long-term sampling control in winter and summer, the Root-Mean-Square error of each ion detection was as follows:

K⁺: 0.51%, Mg²⁺: 0.54%, SO₄^2-: 1.62%, Cl^-: 1.99%, Na⁺: 1.04%

The successful application of the online analysis technology of solid-phase potassium salts by neutron activation method has brought multiple benefits to enterprises:

1. Rapid and accurate elemental analysis: It provides fast and accurate analysis of elemental content in potash, especially for the determination of potassium content, which can give test results every minute, which is crucial for quality control and process optimization.

2. Real-time process monitoring: Technology allows real-time monitoring during production without interrupting the production process, helping to detect and correct abnormal process changes in a timely manner, improving production efficiency and product quality.

3. Cost savings: By reducing the time and cost of laboratory analysis, reducing production costs, while real-time monitoring to help avoid production problems caused by scrap and waste of resources.

4. Comply with environmental regulations: The application of technology to help the industry to strictly comply with environmental regulations, reduce the use of chemical reagents, reduce the impact on the environment,comply with the requirements of sustainable development and environmental protection.

5. Data traceability: The data provided can be recorded and archived to provide support for product quality traceability to ensure that the product meets the standards and regulations to meet customer’s needs.
