lead ore to pure lead making process

  • Lead – Chemical Engineering Materials of Construction

    First, the ore is heated in air called smelting which converts the ore to a compound of lead and oxygen, namely lead oxide (PbO 2). It is then further heated with charcoal. This removes the oxygen away from the lead oxide leaving only lead behind. However, this lead is not very pure which leads to the process of electrolytic refining.

    May 23, 2018· Lead is extracted from its ores by first converting the ore to lead oxide and then heating the oxide with charcoal (pure carbon). The lead produced by this process is usually not very pure and can be further refined electrolytically. Over the past decades, evidence has mounted indicating lead as a significant environmental hazard.

    The PSD shows the problem in attempting to produce lead in a single step. The volatility of PbS and PbO make it desirable to keep the gas volume as low as possible (i.e., use pure O 2 in smelting). But this means operating along the pSO 2 =1 isobar, thus producing a large amount of PbO-containing slag in order to produce a low-sulfur bullion. Producing a low-sulfur bullion requires the use air ...

    Lead is extracted from ores dug from under-ground mines. Lead is also 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 tedious process. First the lead ore is ground into small salt-like particles.

    Lead is obtained from its ores by a method used with many metals. First, the ore is roasted (heated in air). Roasting, also called smelting, converts the ore to a compound of lead and oxygen, lead oxide (PbO 2 ). Lead oxide is then heated with charcoal (pure carbon). The carbon takes oxygen away from the lead …
