Kinetics of iron depletion near pyrrhotite and chalcopyrite inclusions in sphalerite; the sphalerite speedometer

Economic Geology, 1997
The textures and chemical compositions of sphalerite containing chalcopyrite and pyrrhotite inclusions from some skarns, together with experimental data on diffusivity, have permitted rates of exsolution (speedometry) and cooling histories of the skarns to be calculated.

Mineral properties and bacterial leaching of intensively ground sphalerite and sphalerite-pyrite mixture

International Journal of Mineral Processing, 1994
Abstract The intensive grinding of sphalerite or sphalerite-pyrite mixtures accelerates the extraction of zinc from sphalerite by the bacteria Thiobacillus ferrooxidans and as a consequence shorten the process of bacterial leaching. This grinding affects the solid-state properties of the sulphides.

EFFECTS OF pH ON ELECTROFLOTATION OF SPHALERITE

Chemical Engineering Communications, 1996
Abstract Electroflotation studies on sphalerite fine particles, conducted under careful pH control using buffer electrolytes, reveal that for either H2 or 02 electrolytic gases there exists an optimum pH range at which electroflotation is most effective.

Defects in the sphalerite structure

Journal of Physics and Chemistry of Solids, 1962
Abstract Hornstra's method for drawing the arrangements of the atoms in the cores of dislocations in covalently bonded crystals is applied to the sphalerite structure. Bond rearrangement and dislocation dissociation into an extended form are considered and the implications are discussed. A crude calculation of bond strain energy indicates that Haasen'

Crystals with a Sphalerite-Type Lattice

1979
Crystals with a sphalerite-type† lattice, characterized by a tetrahedral distribution of atoms, have a relatively simple crystal structure and are suitable for theoretical calculations. For a long time, these crystals have been the object of study in order to test both old and new theoretical and experimental methods of examining the band structure of ...
