· Lead/zinc mining and smelting activities are some of the main sources of heavy metals emission to the environment [3âˆ'5]. According to a global inventory of trace element emissions by NRIAGU and PACYNA [6], about (357âˆ'857)×10 6 kg/a lead and (462âˆ'1 380)×10 6 kg/a zinc are released into the environment through mining and smelting activities. Globally, the extensive ...

Results show that the ore assays per cent Pb and per cent Zn, mainly occurring in the form of sulfide minerals. Through lead and zinc phase analysis, it is known that the distribution of galena reaches per cent, and that of sphalerite is up to per cent.
Get PriceNearly all zinc sulphide ores carry some lead; the western ores of zinc generally carry silver, and some of them carry both silver and gold. Pyrite, pyrrhotite, chalcopyrite, and galena are very commonly associated with sphalerite in sulphide deposits. The most common gangue minerals are quartz, calcite, and dolomite.

In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 5070%, and the sulfur content of sulfidic ores is in the range of 1520%.
