Sphalerite contains, aside from iron, copper and cadmium, significant amounts of indium (up to 0.38% (w/w)) leading to indium contents up to 70 mg/kg in the mine tailings. …

 · The lead ions from galena were obviously absorbed onto the sphalerite surface, while the zinc and iron ions from sphalerite were not obviously migrated to the galena surface. Principal component analysis (PCA) of a dataset composed of 206 positive ion peaks of galena and sphalerite indicates that the surface components of galena and …

Faceting this material, however, poses a challenge. Sphalerites have a low hardness (3.5 to 4) and perfect cleavage. These properties also make sphalerites less than ideal as jewelry stones. Nevertheless, sphalerites can show beautiful colors and may appeal to collectors of unusual gems. Consult our sphalerite buying guide for more information.

The tailings dam of the Kooshk lead-zinc mine was found to contain approximately 3.64% zinc, and more than 90% of sphalerite was leached within 14 days using mixed bacteria, …

The Kooshk lead-zinc deposit/mine is located in Yazd province, Iran, and its tailing dam contains about 3.64% zinc, 0.97% lead and 24.18% iron. Experiments were designed and carried out by a mixed culture of mesophile bacteria as well as a mixed culture of moderate thermophile strain in the shake flasks.

sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore). The …
