应用化学分析电子光谱ESCA研究煤系、矿系黄铁矿的表面及氧化规律。矿系黄铁矿的S/Fe比较高。煤系黄铁矿含钙,而矽卡岩(Skarn)黄铁矿具有铜,在磷、溴含量上也有差异。两类黄铁矿最大差异在于煤系黄铁矿含碳量高且具有各种形式的碳,反映了煤系黄铁矿与碳质岩共生。研究表明黄铁矿的氧化不可避免,氧化产物除氧化物,羟基化合物,硫酸盐外,还可能具有其它形式。 Application of Chemical Analysis Electronic Spectroscopy to Study the Surface and Oxidation of Pyrite in Coal Measures and Mines. The ore pyrite has a high S / Fe ratio. Coal-based pyrite contains calcium, while skarn pyrite has copper, which is also different in phosphorus and bromine contents. The biggest difference between the two types of pyrite is that coal pyrite has a high carbon content and various forms of carbon, reflecting the symbiosis between coal-bearing pyrite and carbonaceous rocks. Studies have shown that the oxidation of pyrite is inevitable, the oxidation products in addition to oxides, hydroxy compounds, sulfates, but also may have other forms.
