摘要
介绍了接触极化曲线法的原理及基本参数的测取方法 ;通过一些典型极化曲线 ,对矿床氧化状态、电极排布、矿体结构等因素的影响作了分析 ;对所测得的部分典型曲线进行了矿体独立性、反应矿物、反应矿物有效面积、元素储量、元素品位等参数的推断 ,并将推断与勘探结果进行了对比分析。认为接触极化曲线法特别适合导电性硫化矿床 ,是同时兼具直接性。
This paper has described the principle of the contact polarization curve method and the technique for measuring basic parameters, analyzed the influence of such factors as oxidation conditions of the ore deposits, arrangement of electrodes and structures of orebodies on the basis of studying some typical polarization curves, inferred several parameters such as independency of orebodies, reacted minerals, effective areas of reacted minerals, reserves of elements and grades of elements for some measured typical curves, and compared the inferences with the exploration results. It is held that the contact polarization curve method, being an exploration technique characterized jointly by immediacy, long distance and totality, is especially suitable for conductive sulfide ore deposits.
