“…3, H 2 S dominates when pH < 7.0, whereas HS − dominates when pH > 7.0, and S 2− dominates at pH > 13.9 [9,22,28,29]. Thus, we can conclude that HS − species interact with metallic ions on the mineral surface and form a sulfidized surface film, thus activating the flotation of oxide minerals.…”

“…However the selection of reagents is not an easy task due to a number of technical difficulties presented during the process, like the mineralogical complexity of the ore among other aspects. Furthermore, the use of biodegradables reagents is without no doubt one of the necessary actions in the mining metallurgic industry, for which it needs to comply with the necessity of avoiding negative environmental impacts [5,6].…”

“…O-isopropyl N-ethylthionocarbamate (IPETC) is widely used as a flotation collector for sulfide ores, particularly copper and silver ones [1]. Leakage of this compound into wastewater after ore separation is unavoidable.…”
