| 摘 要： | 鉴别锰矿与锰冶炼渣对于锰矿进口贸易和环境保护具有重要意义,由于锰冶炼渣与一些锰矿具有相似的元素组成,都含有锰和硅铝镁钙等杂质元素,仅从元素含量的高低无法准确将其鉴别。本文按国别收集我国主要进口锰矿及不同工艺的主要锰冶炼渣作为研究样品,应用X射线荧光光谱、X射线衍射及傅里叶变换红外光谱技术相结合,建立了锰矿与锰冶炼渣的鉴别方法。在元素组成上,锰冶炼渣的硅含量较高,水淬渣和空气冷却渣的钙含量较高。在物相上,锰矿的特征物相包括软锰矿、氧化锰、方锰矿、菱锰矿等;而锰冶炼渣因为经过冶炼的过程存在硅酸铁、锰橄榄石等特征峰,从而对样品属性进行鉴别。红外光谱显示,锰矿在600~400 cm~(-1)范围内有两个强吸收带,并单独或者同时在1420 cm~(-1)处有特征吸收峰;而锰冶炼渣在960 cm~(-1)左右有宽强吸收峰。本法建立了锰矿的物相谱图库及锰冶炼渣的物相特征,并充分利用红外光谱技术作了有力佐证,确定了锰矿及其冶炼渣的主要区别点。

| Abstract: | It is very important to identify manganese ore and manganese smelting slag for manganese ore import trade and environmental protection. Due to the similarity of elements in manganese smelting slag and some manganese ore, such as Mn, Si, Al, Mg, Ca and other impure elements, they cannot be identified only by the content of the elements. China's main imported manganese ore and the main manganese smelting slag samples were chosen as the research subject, which was studied by X-ray Fluorescence Spectrometry(XRF), X-ray Diffraction(XRD) and Fourier Transform Infrared Spectroscopy(FTIR). The silicon content of the manganese slag is relatively high, whereas the calcium content of the water quenching slag and air cooling slag are relatively high. The phase characteristics of manganese ore include pyrolusite, manganese oxide, bixbyite, rhodochrosite, among others. The phase characteristics of manganese smelting slag include iron silicate and tephroite because of being smelted. The characteristics of infrared absorption show that manganese ore has two strong absorption bands in the range of 600-400 cm-1, and dependently or at the same time has infrared characteristic peaks at 1420 cm-1. Manganese smelting slag has widely strong infrared characteristic peaks at around 960 cm-1. The phase spectrogram database of imported manganese ore and manganese smelting slag in China has now been established. Primary differences between the manganese ore and smelting slag were determined ultimately, and were proved by FTIR. |
