Smelting without a thermometer - Castpics

Smelting without a thermometer Once your lead or wheel weights have melted, give the lead (alloy) just a couple of minutes more heating, then skim off the dross, flux, skim again, and start casting. Once your mould has warmed up to operating temperature and produces shiny un-wrinckled bullets, turn the heat down slightly.

Melting lead, dangers?

Sep 07, 2008 · With the simple precautions of adequate ventilation and hand-washing, this task ought not be dangerous at all. People have been melting lead for ages for shot, fishing weights, printer's type, soldering, and so on without ill effects, except for the most foolhardy of the lot.

Flux lead in the pot? | The High Road

May 03, 2006 · Lead sheeting is pretty much pure lead, but after smelting a good bit, I'd suggest anyone keep their temperature for smelting around the temperatures above, because the lead just smelts better in that range. Jump up above that and it's more aggravating. You won't hurt the lead, but it's easier to work with at lower temps.

Lead smelting - Wikipedia

Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.

Lead Fumes let's settle this. - Cast Boolits

Jul 05, 2011 · Over the years I have seen guys say that one needs to be carefull of the lead fumes given off by molten lead. There were various authorities also that claimed bunk on this. I did some searching and from all I could find there are no fumes from lead unless it is very very hot. I was reading Glens F's book and he referred to lead fumes. He is often mentioned as THE authority on casting.

Secondary Lead Smelting Background Information Document ...

Lead casting is not a substantial source of emissions because the molten lead is well below the fuming temperature of lead. Total uncontrolled metal HAP emissions from all process fugitive sources at a typical smelter may be from 7 to 30 Mg/yr (8 to 32 tpy), depending on smelter capacity. ... There is currently only one electric furnace in use ...

LEAD INDUSTRY PROFILE - ILA - International Lead ...

Smelting - reacting the lead rich mineral with other ingredients, to yield impure metallic lead. This is traditionally done in two stages: roasting in air, turning the lead concentrate (usually lead sulphide) into lead oxide; heating the lead oxide in a blast furnace with coke to yield metallic lead.

Bronze Casting - Metals, Melts and other Mysteries - Blogger

At the melting point, sometimes if there is a lower temperature metal in the alloy, that element can vent off as vapour. Many metal vapours are extremely toxic! The case in point with bronze is that the heavy metals lead and cadmium are commonly alloyed in with the copper. Both are extremely bad for you.
