Fluxing Zinc in the Backyard Foundry – bolis
This wasn't really a surprise since lead melts even lower than zinc. I also tried the sodium chloride and potassium chloride which I had used successfully on aluminum, but they didn't seem to melt at zinc temperature. Most of my research on zinc flux only came up with answers for big industrial processes, using zinc chloride.

Using lead-free zinc alloys for custom castings
Lead-free zinc alloys have a higher melting point than their lead-free pewter counterparts, so manufacturers must have equipment that can generate the temperature needed to melt zinc. Pewter generally begins to soften around 470 degrees Fahrenheit and reaches a fully molten state around 560 degrees Fahrenheit. Ideal casting temperatures are ...

ZnO, ZnCO 3, and Zn 2 SiO 4 are the predominant mineralogical phases in solid wastes bearing zinc. ZnO, ZnCO 3, PbO, PbCO 3, and PbSO 4 can be easily dissolved directly by strong alkaline solutions. However, quite a big portion of zinc in the dust exists as zinc ferrites or zinc sulfide and lead as lead sulfide which cannot be dissolved completely in alkaline solution.
