The galvanic interaction between galena and chalcopyrite enhanced the oxidation of galena, leading to an increase in oxysulfide and hydroxide components on the galena surface. The accelerated oxidation of galena is conducive to the humic acid adsorption, achieving an efficient depression of galena flotation at a short conditioning time.OBJECT HISTORY: Galena. Galena, the official state mineral of Wisconsin, is the raw material used to produce lead. During the Wisconsin “lead rush” of the 1820s-40s, lead was more valuable than gold.
