铜精矿样品的高压密封微波消解方法研究

研究了采用高压密封微波消解技术消解用于成分分析的铜精矿样品的方法。依据铜精矿矿物组成、物相结构，分别选取了有机物含量高、硅含量高和金属氧化物含量高的样品进行试验，试验内容包括消解试剂种类和用量选择，样品完全消解的条件等。根据研究结果建立了适于铜精矿化学成分分析的高压密封微波消解方法。通过对不同矿物组分、不同物相结构的铜精矿样品的完全消解验证实验，证明了该消解方法的实用性。采用该方法消解铜精矿，然后用ICP-AES法检测试液中砷、汞、铅、镉和氟离子选择电极法检测试液中氟，分析结果与国家标准方法的测定结果一致。

Study on high pressure sealed microwave digestion method of copper concentrate samples

A high pressure sealed microwave digestion technique was studied for composition analysis in copper concentrate samples.According to their mineral composition and phase structure,the copper concentrate samples with high content of organic matters,silicon and metallic oxide were used for testing.The experimental content included types and dosage of digestion reagent,the conditions to fully digest the sample,etc.A high pressure sealed microwave digestion method based on the experimental results was establishe...
