江苏某地铅锌锰矿床中锰矿物成分经笔者初步研究确定有菱锰矿、锰方解石的含锰碳酸盐系列,和软锰矿、拉锰矿、水软锰矿、锰胶、硬锰矿、钙锰矿的含锰氧化物系列。笔者在鉴定上述锰矿物的性质和成分上广泛应用了室内矿物研究方法,其中包括镜下鉴定、折射率测定、伦琴射线物相分析、差热分析、失重试验、化学分析和光谱分析。並结合锰矿物成分的研究,笔者同时对上述锰矿物的成因、分布状况、形成顺序和共生关系亦作了初步的观察和分析。最后笔者基於上述的实际工作,作出了五点基本结论。从而为氧化带锰矿石的利用提供了矿物学资料,通过对锰矿物成分及成因的研究,对预测原生矿石的可能成分,提供了可靠的根据。
Manganese mineral composition of Pb-Zn-Mn ore deposit in a certain area of Jiangsu Province A preliminary study of the manganese-containing carbonate series of rhodochrosite and manganese calcite determined by the author has been carried out in the areas of manganese carbonate, pyrolusite, ralanite, pyrolusite, manganose, Manganese oxide series. The authors have extensively applied indoor mineral research methods to characterize the composition and composition of these manganese minerals, including microscopic identification, refractive index measurement, x-ray diffraction, differential thermal analysis, weight loss testing, chemical analysis and spectroscopic analysis. Combined with the study of manganese mineral composition, the author also made a preliminary observation and analysis of the genesis, distribution, formation order and symbiotic relationship of the above manganese minerals. Finally, based on the above actual work, the author made five basic conclusions. Therefore, mineralization data are provided for the utilization of manganese oxide ore. Based on the study of the composition and genesis of manganese minerals, the prediction of the possible composition of primary ore provides a reliable basis.
