“…This demonstrates that the Pb element in the raw Pb 3 O 4 has been self-reduced to Pb 2+ in the CaZnGe 2 O 6 crystal during the high temperature reaction under an air atmosphere. [26][27][28] Since the Ca ions themselves are positive divalent, when Pb replaces Ca ions, divalent Pb ions would be more stable to maintain the charge balance of the system. Fig.…”

“…The most prevalent ores containing these metals are sulfide ores (Moradi and Monhemius, 2011). However, the decrease in the availability of these ores has increased the interest in the utilization of other low-grade and more difficult-to-enrich oxidized and mixed-type ores (Hussaini et al, 2021) and secondary wastes (Tang et al, 2020). In particular, recycling processes have many advantages.…”

“…(For this reason, there are additional problems associated with the processing and disposal of concentration tailings (as well as leaching tailings) of not only zinc ores but also other ores [16][17][18][19][20][21][22]). In recent years, various methods and schemes have been introduced into the lead-zinc ores concentration technology to improve its efficiency and to increase the complexity of the use of the raw materials [23][24][25][26].…”
