  • For the problems of poor homogeneity of intermediate product of gold-loaded carbon, easy to produce the quality dispute for gold analysis data and difficulty to ascertain the best value under the unequal precision measurement condition in gold production, the gray system theory was used to data processing and data analysis in this paper. Based on weight values from the correlation analysis, the gray data processing method was established for defining the weighted mean values. The reliability of the method was tested by practical sample analysis and compared with the traditional statistical methods. The results showed that the method exhibited the moderate precision, was easy to understanding and operation, especially exhibited the advantages in theory and practicability in the case of the confirmation of weighted value of average weighted values for multiple single-value data under the unequal precision measurement condition and was suitable for the measurements with few data and unobvious data distribution pattern.
