Why is the test error of tungsten concentrate so large?

There are several main reasons for the large test error of tungsten concentrate:

1. Uneven sample preparation: Tungsten concentrate contains many elements, such as tungsten, iron, copper, lead, zinc and nickel. If the sample preparation is uneven, it will lead to great test error.

2. Inaccurate analysis method: The content of elements in tungsten concentrate is complex, so it needs to be analyzed by various analysis methods. If the analysis method is inaccurate or improperly used, it will also lead to great test errors.

3. Instrument and equipment problems: Tungsten concentrate testing needs some special instruments and equipment. If the equipment is aged or improperly maintained, the accuracy of the test results will also be affected.

4. Technical problems of operators: The testing process requires operators to have high technical level and rich experience. If the operator is unskilled or inexperienced, the test error will be great. Therefore, in the analysis of tungsten concentrate, we need to pay attention to the sample preparation, analysis methods, instruments and equipment, operators and other issues to minimize errors. At the same time, it is suggested to choose a regular laboratory for testing, and maintain good laboratory management and quality control to ensure the accuracy of the test results.
