Anyone know a good way to seperate Tin from Lead?
ResultElectrorefining tin from an alloy of lead/tin is easy as long as the proportion of tin in the alloy is in the high 90% range. Low voltage, low wattage is best to stop the long "whiskers" of tin from growing and shorting the cell. HCl is used as the electrolyte. Pewter is normally an alloy of tin and copper.
