ادامه مطلبThe ancient Greeks and Romans were able to separate silver from lead about 2000 years ago [2]. Many of the Roman lead ingots were inscribed "Ex Arg" or "Ex Argent" to signify that the silver had been removed from the lead. The Greeks were able to desilver lead to a 0.02 percent silver content and the Romans to a 0.01 percent silver content [3].
