马坞矿区金检测结果可靠性验证
Reliability Verification of Detection Results for Gold Element in the Mawu Mining Area
-
摘要: 马坞金矿分布于岷（县）-礼（县）成矿带的东部，距中川岩体5~7 km，是近年来发现的一个中型微细浸染型金矿床。在对该矿区岩矿标本鉴定时，发现此地金矿存在裂隙金、包裹金的现象，为进一步证实岩矿鉴定结果的准确性，对2个标本分别做了电子探针。结果表明本矿区样品存在裂隙金，最大颗粒粒径达0.05 mm，存在包裹金，包裹体为黄铁矿，数量达5~6颗。在样品的分析过程中由于包裹体的存在，可能会影响检测结果的准确性，笔者通过选择合理的样品制备流程、检测流程、以及分析内、外检结果等几个方面对检测结果可靠性进行分析验证。经采用火焰原子吸收光谱法和火试金重量法方法比对，马坞矿区样品按照微细粒金矿样品加工流程选择合理，选用火焰原子吸收光谱检测方法正确，报告结果准确可靠。Abstract: The Mawu gold deposit is distributed in the east part of Minxian-Lixian metallo genic belt, which is 5~7 km from Zhongchuan rock mass. The Mawu gold deposit is a medium-sized micro disseminated type gold deposit that discovered in recent years. Fissure gold and package gold have been found during microscopy observing process of rock ore specimens. During the analyzing process, the existence of inclusions may be affected the accuracy of the test results. In this paper, the reliability of testing results has been tested and verified by selecting the reasonable sample preparation process, detection process, and analysis of internal and external inspection result.After comparing, the results show that the sample preparation process for Mawu mining area is reasonable, and the related detection results are accurate and reliable.
