OBJECTIVE
To establish the quality assessment method of crude pyritum.
METHOD
The correlations of methods of modern and traditional quality appraisement with density for crude pyritum were investigated.
RESULT
Appraisement of crude pyritum using density as an evaluation index was in accordance with its traditional quality appraisement method. The density had extremely significant positive correlation with FeS2 content contained in crude pyritum (r = 0.990, P<0.001) and became smaller with the decreasing of FeS2 content. Meantime the density also had extremely significant negative correlation with total ferrum content contained in crude pyritum (r = -0.971, P<0.001) and became smaller with the increasing of total ferrum content.
CONCLUSION
It's feasible to take density as evaluation index for quality control of crude pyritum, and the testing method established is simple and convenient.
目的
建立生自然铜的质量评价方法。
方法
考察生自然铜现代与传统质量评价方法与密度的相关性。
结果
以密度为评价指标对生自然铜进行评价，与传统质量评价方法相符。密度与生自然铜中FeS₂含量呈极显著正相关（r = 0.990，P<0.001），随FeS₂含量降低而减小。同时密度与生自然铜中总铁含量呈极显著负相关（r = -0.971，P<0.001），随总铁含量增加而减小。
结论
以密度为评价指标控制生自然铜质量可行，所建立的检测方法简便易行。
