This standard specifies methods for the determination of copper content in pyrite and sulphur concentrates using flame atomic absorption spectroscopy (AAS) and Spectrophotometric method, spectrophotometry, for samples with copper content in the range of 0.01% to 1%. The standard describes in detail the methods for preparing, dissolving and analyzing the samples to ensure the accuracy and reliability of the determination. This provides a scientific basis for the detection of copper content in mineral products, which is helpful for mineral product quality control and evaluation.
