拉曼光谱和拉曼图象分析一般是非破坏性分析技术 ,它可用于鉴定矿物和宝石。拉曼光谱分析是灵敏度高的方法 ,它只需要少量的代表性样品 ,它适用于块状矿石、细粉末和水溶液等样品分析。因为玻璃和水是拉曼光弱的散射物质 ,所以可获得空气中的样品、玻璃中的样品或浸在水中样品的拉曼光谱。讨论了在矿物加工中应用拉曼光谱鉴定矿物的实例。其中包括 :检测轻金属矿物 (如碳和氟 )、区分硫化铁矿物的同质异象、含少量元素矿物的特性 (如闪锌矿中的铁 )、鉴定硅酸盐、氧化物和碳酸盐脉石矿物。拉曼微探针也可用于拉曼图象分析及面和包体扫描分析。提出了金刚石拉曼图象分析实例
Raman spectroscopy and Raman image analysis are generally non-destructive analytical techniques that can be used to identify minerals and gems. Raman spectroscopy is a highly sensitive method that requires only a small number of representative samples for sample analysis such as lump ore, fine powders and aqueous solutions. Because glass and water are Raman light scattering materials, samples in air, samples in glass, or Raman spectra of samples immersed in water are available. An example of the use of Raman spectroscopy for the identification of minerals in mineral processing is discussed. These include the detection of light metal minerals such as carbon and fluorine, the homogeneity of the iron sulphide minerals, the characterization of minor elemental minerals (eg, iron in sphalerite), the identification of silicates, oxides and carbonic acid Salt stone mineral. Raman microprobe can also be used for Raman image analysis and surface and body scan analysis. An example of diamond Raman image analysis is presented
