Beneficiation - an overview ScienceDirect Topics

Bacterial Depyritization of Sphalerite and Galena. Beneficiation of complex base metal sulfide ores is based on selective production of individual clean concentrates of copper, zinc, and lead. Sphalerite flotation through copper activation becomes complicated when other minerals such as pyrite can get inadvertently activated.

Sphalerite - an overview ScienceDirect Topics

After the precipitate has grown to a certain size it becomes more favorable for the sphalerite to transform or to continue growth as wurtzite ZnO on the four tetrahedral planes, providing the right “epitaxy” for the sphalerite and a (low energy) basal plane in contact with the metal. In some grains most of the precipitates contained sphalerite, which means that for some particular oxidation parameters or Zn concentration sphalerite

Sphalerite Article about sphalerite by The Free

sphalerite (sfăl`ərīt, sfā`–), mineral composed of zinc sulfide, usually containing some iron and a little cadmium.It occurs in crystals of the isometric system but more generally in cleavable, compact masses. It is transparent to translucent and varies greatly in color, iron-free specimens being pale yellow and those with iron being brown, red, black, or green.

Surface chemical studies on galena and sphalerite in

Adsorption and electrokinetic studies were carried out to examine the surface chemical changes on galena and sphalerite before and after interaction with Thiobacillus thiooxidans (T. thiooxidans). The adsorption density of bacterial cells onto the two sulphide minerals was found to be independent of pH, although an increased number of cells was adsorbed onto galena compared to sphalerite.
