I've been reading gobs of threads and find plenty of advice to stir back in any tin that skins on top.
And also to remove any zinc from the melted alloy, and you can use sulfur to pull out the zinc.
From my research I found that these metals melt at:
- Melting point of Lead- 621.43*F
- Melting point of Antimony- 1167.13*F
- Melting point of Tin- 449.47*F
- Melting point of Zinc- 787.15*F
I'm going to be smelting/ liquefying 4-5 5 gal. buckets of range scrap for my first "smelting" job. This to eventually cast 9mm boolits and powdercoat them with safety ever in mind.
With all of my reading I haven't found answers to these questions-
- Is there a maximum temperature you stay below when smelting range lead?
- Do you constantly stir in the skinned Tin so it doesn't stick to the dross (range junk) as you spoon it out, or pull the skins out and place them into something while removing all the dross and add then back in after finishing fluxing and removing the zinc?
- Or is anyone worrying about the zinc, maybe its fine to leave it in? - 787* to get it out wow!
I haven't found anything anywhere to give the procedural steps like this when smelting.
Thanks guys.
