破山银矿床氧化作用的强度和深度受气候、地形、构造、矿石成分、围岩性质等区域因素及局部因素控制。据矿石中银的赋存状态,银、铅呈正相关关系,以及目前国内尚无银精矿产品,矿石技术加工等原因,指出据方铅矿氧化率来划分银矿石的氧化程度具实际意义。并阐述了本矿床氧化带、混合带、原生带的分布特征及各相带中矿石的结构、构造、矿物成分及银的赋存状态。通过本矿床氧化程度的研究,根据大量实际资料,充分考虑多种自然因素对氧化作用的影响,以铅相测试数据为基础,综合分析研究后划分的氧化带、混合带、原生带界线,基本上揭示了客观规律。
The strength and depth of oxidation of the Pushan silver deposit are controlled by the regional factors such as climate, topography, tectonics, ore composition, surrounding rock properties and other local factors. According to the occurrence state of silver in the ore, silver and lead have a positive correlation, and there are no silver concentrate products and ore processing in China so far. It is pointed out that the oxidation degree of silver ore has practical significance according to the galena oxidation rate. The distribution characteristics of oxidation zone, mixed zone and primary zone in this deposit and the structure, structure, mineral composition and silver occurrence status of ore in each phase are expounded. Based on a large amount of actual data, the influence of many natural factors on the oxidation is considered. Based on the lead phase test data, the oxidation zone, mixed zone and primary zone boundaries after the study are comprehensively analyzed. Revealed the objective laws.
