Natural galena whiskers

Journal of Crystal Growth, 1970
Abstract Natural galena whiskers have been observed in the hydrothermal polymetal deposit of “Mogilata”, Madan ore district, Bulgaria. Using optical goniometric and X-ray techniques there have been determined [100] and [110] whiskers, as well as different kinked whiskers connected with the change of the growth direction.

The photoelectrochemistry of galena

International Journal of Mineral Processing, 1994
Abstract The photoresponse of galena to chopped illumination has been studied to elucidate the surface oxidation of this mineral relevant to flotation. The results substantiated previous findings that sulfur remains in the mineral lattice during the initial stages of oxidation.
