Introduction

Copper concentrate is the main raw material for the production of cathode copper. In the non-ferrous field standard system, the determination method standards for the chemical composition of copper concentrate are important in ensuring the copper Concentrate product quality plays an important role. This series of method standards serve the production, trade and application of copper concentrate and provide a solid foundation for my country's non-ferrous gold industry.

Provide technical support for the high-quality development of the industry. GB/T 3884 "Chemical Analysis Methods for Copper Concentrates" aims to describe the contents of copper, gold, and Methods for determining the composition of different chemical elements such as silver, lead, zinc, etc. As the demand for copper consumption continues to increase, the output of copper concentrate is also increasing.

In order to meet the industry's needs for the production, trade and resource recycling of copper concentrate products, and to increase the reliability and comparability of test results, Mining It is of great significance to use inductively coupled plasma atomic emission spectrometry to quickly and accurately determine the content of various elements in copper concentrate.
