Crystal description. sphalerite is a zinc iron sulphide mineral and a major ore of zinc. sphalerite is also known as blende or zinc blende. when pure with little or no iron it forms clear crystals, usually red known as ruby blende, but as iron content increases it forms dark, opaque metallic crystals known as
Sphalerite is named after greek word for quotmistakenquot, because the mineral was often mistaken for galena, but contained no lead. sphalerite forms clear crystals with colours ranging from pale yellow to orange and red shades, with the presence of iron it forms dark, opaque metallic crystals.

The established lead-zinc ore flotation processing scheme is to add zinc sulphate znso4 to the grind to control metal ion activation sphalerite depression. often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
Sphalerite the primary ore. sphalerite zinc sulfide is the primary ore mineral from which most of the worlds zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. much of the early zinc production was from nonsulfide deposits however, as these resources were exhausted, production shifted to sulfide deposits.
Numerous minerals occur associated with sphalerite in veins of zinc ore, one of the commonest of these being galena. the more important of the other associated minerals are calcite, dolomite, siderite, pyrite, chalcopyrite, and barite. sphalerite frequently contains small amounts of cadmium sulphide, and the cadmium of commerce is obtained from ...
