Some times one might be at the right place and the right time. I have a line on 3,000 pounds +/- of "lead" from a manufacturing process. The shop thinks it has lead/tin in it. Borg steel tells me its pure lead but because it is in 40 to 50 pound chunks heaped into a bucket, they are lowballing any value. They would not let me look at the screen of the analysis gun to see the "trace" elements. Sending off a small sample to a guy on CastBoolits to get an analysis.
I made a rough calculation of the volume of one of the chunks. as pure lead it should weight over 100#. It weights 50#. It could have some voids due to it being poured cold but I would not think 50%. It melts with a small soldering iron so do not think it is zinc. Using lead pencils, it is in the H to F hardness range. Pure lead is 5B or softer so it is medium hard.
I have been watching the want adds for a old sailboat that is being scraped out. The lead keels typically have between 3% and 6% antimony. I have plenty of Lino and solder with tin. 1,000# of high antimony lead from a keel and I could stop looking for more lead.
It will take over a week to get the analysis back. it will be interesting as to what it is.
