The Silver Extraction Process - athens123
The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore ...

Silver mining - Wikipedia
Silver has been known since ancient times. Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC. The silver mines at Laurium were very rich and helped provide a currency for the economy of ancient Athens, where the process involved mining the ore in underground galleries, washing and then smeltingit to produce the metal. Elaborate washing tables still exist at the sit

MINING SILVER - How Is Silver Mined?
The main method of silver extraction is the cyanide process, aka cyanidation: 1. The ore is crushed into pieces to expose the silver. 2. About 1.4-2.3kg of lime (calcium hydroxide, Ca(OH)2) is added to every ton (1000kg) of silver ore to create an acidic environment. 3. Cement is added into the mixture, as well as water or a cyanide (CA-) solution.
