Study on the Interaction between Galena and Sphalerite

Jul 23, 2019· In Pb-Zn ore flotation, unintentional activation of sphalerite often leads to difficult separation of Pb and Zn minerals, during which grinding plays a key role in unintentional activation.

Correlation between the hydrogen peroxide formed during

Jan 01, 2019· Flotation separation of sphalerite from chalcopyrite is significantly affected by the oxidation of metal species on the surface of sphalerite, partially contributed by production of the reactive oxygen species hydrogen peroxide (H 2 O 2) and hydroxyl radicals (OH) if any during wet grinding of a complex sulphide ore.This research experimentally measures the production of H 2 O 2 during

Collectorless flotation of chalcopyrite and sphalerite

Mar 01, 1981· The flotation of chalcopyrite and sphalerite from copper and copper-zinc ores has been achieved without using thiol-type collectors. Typically, a sulfide ore sample is first treated with sodium sulfide either during grinding or during the preflotation conditioning period, and then the chalcopyrite is floated with frother alone.

Wisconsin Geological & Natural History Survey » Sphalerite

ONEIDA COUNTY: Sphalerite is a major ore mineral in the massive sulfide deposit on the Pelican River east of Rhinelander (Sec. 29 T36N R9E). It is most abundant intergrown with pyrite and chalcopyrite in the lower zone of the ore body (Mudrey, 1979).


Sphalerite ((Zn, Fe)S) is a mineral and ore of zinc. It consists largely of zinc sulfide in crystalline form but contains variable iron; when iron content is high, sphalerite is an opaque black variety called marmatite. Sphalerite is found in association with the minerals galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite and fluorite.
