Chemical Formula: FeCr2O4. Description: Chromite is the most important ore of zinc. Chromite is black, translucent and opaque with a brown streak. ... Used in mildew resistant element in some paint. Sphalerite is used in dyes, medicine, and more. Sphalerite is important because it's the most important ore of zinc. Its light dispersion: …In the temperature range of 650–800 °C, the rate-controlling step was the chemical reaction between the zinc sulfide and oxygen with an activation energy of 103 kJ mol −1. On the other hand, in the temperature range of 850–950 ° C, the rate-controlling step was oxygen diffusion with an activation energy of 50 kJ mol −1 .About sphalerite – introduction and history. Sphalerite is a zinc ore containing iron When its iron is high, its color becomes matte black Materials that have the quality of jewels have less iron content and as a result their crystals are transparent. Due to its low hardness, it is considered a gem for collectors

Mineral Description. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products. Hematite's Streak: All specimens of hematite will produce a reddish streak.
