中文摘要：
黄铁矿是热液型金矿床中最主要的载金矿物之一,其物性特征在很大程度上指示了金的富集规律。采用BHMR-08型半导体矿粒调温电阻测试分析仪测量了胶东玲珑金矿的黄铁矿电阻率。结果表明,50~60℃测试条件下,所测黄铁矿电阻率值变化幅度最小,说明上述温度是测黄铁矿电阻率的合适温度范围。在此工作基础上,系统测量了玲珑金矿47号脉不同标高的14件黄铁矿样品的电阻率,结合该脉金的富集特点发现,黄铁矿电阻率为0.4~0.8Ωm时含金性最大。
英文摘要：
Pyrite is a main gold-bearing mineral in hydrothermal gold deposits,and its physical property may indicate the enrichment grade of a gold deposit.Resistivity of pyrite obtained from the Linglong gold deposit was measured using a semiconductive mineral based temperature-controllable resistivity analyzer.The result showed that the smallest variation of measured pyrite resistivity was appeared when the measuring temperature was of 50—60℃,indicating that the best temperature for measuring pyrite resistivity is about 50—60℃.This study systematically measured resistivity of pyrite in the 47th lode of the Linglong gold deposit and explored the correlation of resistivity and gold content of pyrite.The result showed that the gold content in pyrite reaches the highest value when pyrite resistivity is about 0.4—0.8 Ωm.
