Sphalerite is an important ore of zinc; around 95% of all primary zinc is extracted from sphalerite ore. [42] However, due to its variable trace element content, sphalerite is also an important source of several other metals such as cadmium, [ 43 ] gallium, [ 44 ] germanium, [ 45 ] and indium [ 46 ] which replace zinc.
