| Abstract: |
| A sample declared as "copper concentrate" was analyzed by X-ray fluorescence spectroscopy, X-ray diffraction and other techniques, combined with super depth-of-field microscopy and scanning electron microscopy for appearance, elemental composition, physical phase composition and microscopic morphological composition. The results showed that the sample contained natural minerals such as pyrite, quartz, malachite, willemite and talc, as well as a large amount of micron-sized spherical zinc oxide, glassy sodium-calcium-silica-aluminate, loose colloidal silicate and striped and flaky copper metal chips. The characteristics of the sample was significantly different from those of copper concentrates, showing a mixture of natural minerals and a variety of smelting and processing products. |
