摘要
黄色菱锌矿,俗称"火鸡油"。本文采用常规的矿物学研究方法和电子探针、红外吸收光谱、激光拉曼光谱等测试方法,对菱锌矿矿物学特征进行研究。结果表明"火鸡油"的颜色呈浅黄色、豆黄色到鲜艳的金黄色;呈玻璃到油脂光泽,折射率为1.74(点测法),相对密度为4.198~4.330;主要成分是ZnCO_3,并含有少量的Fe、Cd、Ca等微量元素,Cd是引起黄色的主要原因;具粒状结构,薄片单偏光下呈无色、灰色;红外吸收光谱在1430cm^(-1)、865cm^(-1)和740cm^(-1)附近有碳酸盐矿物的特征吸收峰;激光拉曼光谱在300cm^(-1)、730cm^(-1)、1090cm^(-1)附近有方解石族的拉曼特征峰。黄色菱锌矿的硬度不高,化学性质不够稳定,并且含有微量的镉,镉元素会对人体有一定的危害。
Yellow ling zinc ore, commonly known as "Turkey oil". In this paper, the mineralogical characteristics of the mineralogy of wuling were studied by using conventional mineralogical research methods and electron probes, infrared absorption spectra and laser Raman spectroscopy. The results show that the color of "Turkey oil" is yellowish yellow and yellow to bright yellow. The refractive index is 1.74(point measurement), and the relative density is 4.198 ~ 4.330. The main component is ZnCO_3, and contains trace elements of Fe, Cd and Ca. Cd is the main cause of yellow. With granular structure, the thin sheet is colorless and grey. The infrared absorption spectra were characterized by the characteristics of carbonate minerals near 1430 cm^(-1), 865 cm^(-1) and 740 cm^(-1). The laser Raman spectra of the Raman characteristic peak in the vicinity of 300 cm^(-1), 730 cm^(-1) and 1090 cm^(-1) were found. The hardness is not high, the chemical property is not stable, and it contains trace cadmium, which can be harmful to the human body.
