GB/T 3884.14-2012 《Methods for chemical analysis of copper concentrates - Part 14: Determination of gold and silver - Fire assay gravimetric and flame atomic absorption spectrometric method》 Related products

GB/T 3884.14 - 2012 is the 14th part of the series of standards for chemical analysis of copper concentrates. This part stipulates the determination of gold and silver content in copper concentrates by fire test gold weighting method and atomic absorption spectroscopy (AAS) method. The content of gold and silver affects the value of copper concentrates and subsequent processing. The standard provides standardized operation procedures, can accurately determine, help enterprises evaluate the quality of copper concentrates, rationally price, ensure fair transactions, and provide an important basis for mass control and cost accounting in the production, trade and smelting of copper concentrates.
