Sphalerite - Wikipedia

Economic importance. Sphalerite is the most important ore of zinc. Around 95% of all primary zinc is extracted from sphaleritic ores. However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium,, gallium germanium, and indium.. Gemstone use. Crystals of suitable size and transparency have been .
