Assaying is the process of analyzing a material, often a metal or mineral, to determine its composition and quality. This technique is commonly used in mining and metallurgy to assess the value of ores and to ensure that the extracted materials meet specific standards. The results of assaying help companies make informed decisions about processing and selling their products. Various methods, such as fire assay and chemical analysis, are employed to accurately measure the concentration of valuable elements like gold, silver, or copper in the sample.
