Electrobioleaching of sphalerite flotation concentrate
Minerals Engineering, 1998Electrobioleaching of a sphalerite flotation concentrate at a positive DC potential of +0.4V (SCE) has been discussed and compared with that at -0.5V(SCE). Probable mechanisms in the electrobioleaching process are considered with respect to oxidative and reductive dissolution as well as to direct and indirect roles of Thiobacillus ferrooxidans.

Sphalerite Framework in Polar Sulfides
Journal of Chemical Crystallography, 2013The basic sphalerite framework has been revealed in complex sulfide minerals: galkhaite, stalderite, aktashite and other sulfide compounds. It has been shown that the noncentrosymmetric sphalerite framework is very stringent and robust in reference to the cation type, cluster formations and the presence of vacancy.

Defects in the sphalerite structure
Journal of Physics and Chemistry of Solids, 1962Abstract 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'
