煅自然铜二硫化铁成分变化的研究

FeS_2 Changes in Ignited Pyritum

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。

FeS_2 changes in Pyritum during igniting process were studied systematically by comparing Pyritum ignited under different conditions in terms of S cotent, Fe content, yeilding ratio of ignited product and appearance features. Calcined Pyritum samples purchased from various parts of China were also compared in regard to theit quality.
