This chapter discusses the methodology for characterisation and identification of the minerals defined and selected in Chap. 133 as common gangue minerals. As shown in the compilation presented (Table 134.1), the very low reflectance of most gangue minerals (either measured or reckoned by the Fresnel equation) distinguishes them clearly from the metallic ores.
