IN the Parkes process of lead refining, after desilverization has been completed by means of the addition of zinc, there remains in the lead from 0.5 to 0.6 pct zinc. At this stage in the refining operations virtually all impurities are reduced to refined lead specifications except zinc and antimony. All excess copper, nickel and cobalt have been removed by the zinc additions. The …

I've read that you can reduce lead oxide to lead by heating it with carbon. Does this also work with lead dioxide? ... this sounds more dangerous then creating a old style coke forge to take it up to 1200 then collect the lead from the bottom once cooled. Then refine it. $endgroup$ – jonboy79. Commented Jul 27, 2020 at 10:13.

How to convert oxide to element concentrations or vice versa? The conversion from oxide to element or element to oxide is straight forward. All we need are the atomic weights of the involved element and oxygen, which can be easily been taken from any good Periodic Table of Elements (e.g., IUPAC). As an example, let's convert SiO 2 to Si:. Firstly, we need the molecular …
