GB 2466-1981Pyrites and concentrate -- Determination of copper content -- Flame atomic absorption spectrometric and spectrophotometric methods (English PDF)

Foreword

This standard replaces GB/T 2466.1-1996 "Determination of copper content in pyrite and concentrate - Part 1. Flame atomic absorption spectrometry Act "and GB/T 2466.3-1996" Determination of copper content in pyrite and concentrate - Part 3. BOC spectrophotometry, "the two Standard merged into a standard, divided into two methods.

This standard is proposed by China Petroleum and Chemical Industry Association.

This standard by the Chemical Industry Standardization Technical Committee of mineral ore centralized.

This standard was drafted. Blue Blue Sea Design Institute.

1 Scope

This standard specifies the flame atomic absorption spectrometry and spectrophotometric determination of pyrite and sulfur concentrate copper content.

This standard applies to pyrite and sulfur concentrate products in the determination of copper content of 0.01% to 1%.
