Lead melts at 621.5 F. I melted the wheelweights over my Coleman stove and pore my ingots. Some looked weak and 2 even broke. Malleability was not there. If I do have a zinc contamination can I separate the zinc from the lead by remelting the ingots at a temperature above 621 but below 787? I am usingWheel weight lead that contains Zinc - how to deal with,Aug 14, 2013· I got about 100lbs of weights awhile back and I spent LOTS of time sorting through them to separate the lead from the zinc and iron.
