Floatation separation of galena, sphalerite, and pyrrhotite by combined depressant CCSL
工程科学学报, 2017 The flotation separation of galena, sphalerite, and pyrrhotite was investigated with CCSL as a depressant. Flotation test results show that galena and sphalerite can float but pyrrhotite can barely float with CCSL as a depressant.

Recrystallization of galena on heating
The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1961 The author have investigated the crystallinity of galena by means of x-ray spectrometer. It was found that galena showed structural plasticity on heating and grinding. The main results obtained were as follows: (1) Recrystallization of galena on gentle heating was clearly observed from diffraction peak profile, and the crystallinity was increased in ...

Quantitative leaching of galena
Bulletin of the Chemical Society of Ethiopia, 2000 Abstract (Received September 25, 1999; revised January 19, 2000) Experiments on the quantitative leaching of lead from galena in hydrochloric acid solutions are reported. The effects of contact time, acid concentration, number of leaching stages, solid to liquid ratio, particle size, temperature, and stirring speed, on the leaching reaction are ...
