Oct 18, 2023 · Sphalerite is a mineral, mixed with zinc and iron sulfide. The chemical formula of Sphalerite is (Zn, Fe)S. The dispersion of sphalerite (0.156) is three times that of diamond, which has a dispersion of 0.44. When the content of iron is high, sphalerite is often found in opaque black known as marmatite. The material used for the present study is a natural pure sphalerite from southwest Yunnan province of China. The material was soaked in a 1% concentration of hydrochloric acid solution for 1 h, cleaned with ultrasonic and then air-dried; after that, it was hand-ground in a mortar and pestle, and sieved to obtain a fraction with a particle size range of 40–75 μm.A very large hexagonal calcite growing out of a sphalerite matrix, this is simply a spectacular specimen. The crystal is 15.5 cm wide, rises 7 cm above the sphalerite matrix, and is 4-5 cm thick. The sphalerite matrix is about 5 cm thick. The specimen weighs 2.4 kg. The color in the photo is very accurate, with a subtle pink and light ...
