Anybody done this? The range I go to hasn't done it ever as far as I can determine. I am working on them to allow me to do it. I have a small Kubota tractor that I can use to move material around with but I need some ideas on how to separate the lead out from the soil. The site is mainly sandstone and shale, so there are lots of large (bullet size) particles of rock in there as well as sand and dust to separate. Once I get the lead separated I have a small foundry I can use to melt it all down into ingots. The big issue is getting it off the range. Any ideas?
