Central Kentucky Mineral District

Sphalerite is the primary ore mineral that has been mined from the vein. The sphalerite in the Tyrone Limestone is black and has a high cadmium content, although black and reddish-orange sphalerite has also been obtained from mud caves along this vein. The sphalerite in the Tyrone, Camp Nelson and Oregon formation contain, cadmium.

Sphalerite

Sphalerite is a mineral that is often found in zinc deposits and is the primary ore of zinc. It is a sulfide mineral with a chemical formula of ZnS and has a hardness of 3.5-4 on the Mohs scale. Sphalerite typically has a brown or yellowish-brown color, but can also be found in shades of red, green, black, and white. ...

Sphalerite

Weisener (2002) observed increased rates of oxidation and increased acid consumption as a function of the amount of solid-solution iron in sphalerite [(Zn,Fe)S]. Apparent activation energies of 21–28 kJ mol –1 obtained at 25–85 °C are similar to the values reported by Rimstidt et al. (1994). Weisener et al. (2003) suggested that the production of polysulfide …

Sulfide Minerals

Sphalerite can be found in many ore veins of sulfide minerals, commonly associated with galena and pyrite. Miners call sphalerite "jack," "blackjack," or "zinc blende." Its impurities of gallium, indium and cadmium make sphalerite a major ore of those metals. Sphalerite has some interesting properties.

Common Fluorescent Minerals

Sphalerite. While most fluorescent specimens of the mineral exhibit an orange fluorescence, sphalerite can fluoresce in a rainbow of colors.
