but it contains much ore that is so fine grained thatconventional processing cannot effectively separate the ore and gangue minerals. Very finegrained sphalerite and pyritethat aredifficult toseparate and recover prevented efficientprocessingofthe possible to that ofthe individu al metalbearing mineral particles.This process
Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
Sphalerite also serves as the most important source of cadmium, which is recovered as a byproduct of the zinc smelting process. In rare cases when the mineral is transparent, sphalerite has been cut as a gemstone, showing off its very high refractive index. Return to the Mineral Collectors Information Page

The activation of sphalerite particles by ammoniacal copper solution (ACS) was investigated in this study. This microflotation study was conducted on a single sphalerite mineral with the particles size of 38 μm to 75 μm. Results showed that ACS has somewhat better activation effect than copper sulphate (a traditional activator) with sodium isobutyl xanthate as the collector.

Sphalerite is the principle ore of zinc. In some localities, it occurs with significant amounts of the rare elements cadmium, gallium, and iridium, and it is also the main ore of those metals. Sphalerite is an important mineral to collectors, and some transparent varieties are occasionally faceted for collectors.
