Development of a Quality Control Sample for Analysis of Multi-metal Contents in Gold Ore
Quality control sample is widely used in chemical analysis as one of the most effective quality control methods.To ensure the accuracy and effectiveness of multi-element detection results in gold ore,a gold ore quality control sample was designed and developed in this work,and the values of gold,silver,copper,lead,and zinc were determined.The proposed gold ore quality control sample has undergone sample preparation,homogeneity tests and stability tests.Then,the fire assay atomic absorption spectroscopy and acid digestion atomic absorption spectroscopy are used to determine the value.The determined values are accurate and reliable,with reasonable uncertainty assessment.Compared with similar quality control sample,it has the characteristics of multiple types of elements and a wide range of content,which can provide technical support for the accurate determination and traceability of related elements in gold ore samples.
