With the depletion of natural mineral resources, secondary resources such as zinc leaching residue (ZLR) should be processed to recover valuable metals. In this study, flotation recovery of lead (anglesite) in ZLR from a zinc smelting plant was investigated, and the mechanism studied by using Fourier-transform infrared (FTIR) spectroscopy measurements. The flotation results indicated lead recovery...
The flotation behavior of anglesite at different pulp pH levels was studied, with salicyl hydroxamic acid (SHA) acting as collector. The results demonstrated the effectiveness of SHA over a wide pH range. Zeta potential, adsorption, and x-ray photoelectron spectroscopy measurements were carried out to explore the interactions between SHA and anglesite. The results showed that the adsorption of SHA...
With the increasing consumption of zinc and the depletion of zinc sulfide ores, the exploitation of low-grade zinc oxide ores may be important for the sustainability of the zinc industry. Hemimorphite, a zinc hydroxyl silicate hydrate, is a significant source of Zn and Pb. It is difficult to obtain Zn and Pb from the hemimorphite using traditional technology. In this work, for the first time, sulfidation...
