Only option with fire is Cupel.
You can maybe slag off some of the Lead/base metals with the correct flux.

Do you need to add Lead in the first place?

as a collector i guess. should i try smelting without a collector? if so would i let it cool and break it out or poor it?

No if you insist on using fire the only option is smelting with flux.
How do you concentrate your ore and do you have a proper assay?
