The internal and external inspection system of the analytical sample is an important measure to ensure the quality of the basic analysis, and is also the basis for evaluating the effectiveness of a laboratory. At present, the number of internal inspection samples of the general heap leaching field accounts for 20% to 30% of the number of basic analysis samples, and is used to check the accidental error in the analysis of the laboratory interior. The number of external inspection samples accounts for 5% to 10% of the basic analysis number to find systematic errors in the analysis.
