description The preparation and valuing method of the molybdenum raw ore standard sample comprises the following steps: selecting a molybdenum raw ore standard sample raw material with the particle size of less than 200 microns, grinding, crushing, screening and uniformly mixing to obtain the standard sample; carrying out sample uniformity test through sampling, and carrying out cooperative valuing; and carrying out mathematical statistical analysis test and uncertainty calculation on the fixed value data to obtain the characteristic quantity value of the content of each element of the molybdenum raw ore standard sample. According to the method, the sample uniformity is good, seven qualified laboratories adopt different principles, accurate and reliable methods cooperate to fix values, and the determined standard values are accurate and reliable. The sample stability is good, and the effective storage life can be 10 years. The standard sample is reasonable in component design; the development of the standard sample suppl
