Galena ore

To eliminate the adverse effects of traditional galena ore flotation methods, such as high reagent cost, complex operation process, and a large amount of wastewater, a S-HGMS technology was proposed to prepare high-class standard lead concentrate from galena ore. The obtained lead concentrate meets the standard of level I in YS/T319–2013..
