  • Lead and Zinc Smelting - IFC

    Lead and Zinc Smelting Industry Description and Practices Lead and zinc can be produced pyrometal-lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra- tions can be 50–70%, and the sulfur content of ...

  • Zinc smelting - Wikipedia

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

  • Zinc Safety - Periodic table

    The partial pressure of zinc vapor above just-molten zinc is about 2500 times lower than it is near the melting point of typical brass alloys. And a pot of molten zinc rapidly forms a skin of solid zinc oxide slag, which probably reduces the actual pressure of zinc vapor to zero, except when the metal is freshly stirred or poured (and then it is still only 1/2500 the amount generated by brass ...

  • Fluxing Zinc in the Backyard Foundry – bolis

    Being a lower-temperature melt than aluminum, I figured zinc was going to need a different flux. My dad said he had fluxed molten lead using soap or candle wax.

I also tried the sodium chloride and potassium chloride which I had used ...

Hold the temp there..should be near the 621 mark or allow it to get near 700 for faster melting. Add a relatively small amount (compared to the current puddle size) so it does not cause to much of a temp change. Lead will melt into the puddle ...
