are used for production of lead zinc depending on the type of raw material used as a charge. 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 50-70%, and the sulfur content of sulfidic ores is in the range of 15-20%.

The zinc is scrubbed from the vapour in the condenser via liquid lead. The liquid zinc is separated from the lead in the cooling circuit. Approximately 5,000 metric tons (5,500 short tons) of lead are required each year for this process, however this process recovers 25% more lead from the starting ores than other processes.

Extracting Lead Materials from Ore - Lead Shielding, Lead ...

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.

Zinc - Essential Chemical Industry

Under the conditions in the furnace zinc is a vapour (gas), whereas lead is produced as a liquid by a similar series of reactions.. The other components of sinter such as silica (SiO 2), lime (CaO), alumina (Al 2 O 3) and iron oxide (Fe 2 O 3 /FeO), form a molten slag of silicates. This is tapped from the hearth of the furnace simultaneously with the lead, and then separated in a vessel called ...
