My last smelt was 5-3gallon bucket's.

A little detail, you aren't smelting, you are melting. Smelting is extractive production of a metal from its ore, in most cases with the addition of various (nasty) chemicals, additives, and/or high temperatures, producing really nasty byproducts/smoke/fumes that need to be treated with scrubbers, etc..

You might want to also avoid using the word "smelting" anywhere near a ministry of environment inspector....... They will get very excited and start asking you for your environmental permits and certificate of approvals for your "smelting" operation ........ If you think the CFO is picky about things like ranges, you ain't seen nothing.

Its a rcbs promelt with the setting dial on the side. Playing with more chemicals to me sounds like too much grief. I can take the time to get rid of the zinc. Or at least dilute it down. Its 24 hours now and still coughing,at least cant taste the burnt paint/lead now..

Dilute it down.....do you own the Lyman bullet casting handbook?..... 0.01% by weight of zinc will ruin your lead completely.
And you realy shouldn't melt lead in an inadiquatly ventilated area regardless of how much paint,grease, valve stems, bead sealant, or zinc might be in them.

You might be able to mix sulphur into the semi molten metal, then slowly increase temp until it floats, then decrease temp until the sulphur floats and solidifies solidifies on top of the lead. (btw, this is sort of smelting, but might be better described as refining....)

The sulphur will react with the zinc to form zinc sulphide. But to do so, the sulphur must be completely mixed with the lead for it to react. This is not just fluxing the surface of molten lead.

I hope you have some downrigger ball moulds handy, cause zinc polluted lead ain't
worth the effort to try to dillute or purify for bullet use......cannon balls ok.
