通过对不同炮制条件下煅自然铜总S含量、总Fe含量、收得率、外观性状的测定与比较,对煅制时自然铜主成分FeS_2的变化进行了较系统的研究。对不同地区生、煅自然铜的质量进行了比较。
Through the determination and comparison of the total S content, the total Fe content, the yield rate and the appearance characteristics of calcined natural copper under different processing conditions, a systematic study of the change of the main component of natural copper, FeS_2, during the fuming process was performed. The quality of natural and calcined natural copper in different regions was compared.
