    Mining and concentrating. Silver-bearing ores are mined by open-pit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30- to 40-fold concentration of mineral values is usually achieved. Of the three major types of mineralization, lead concentrates contain the most silver and zinc concentrates ...

    While many technologies exist, Silver is typically mined through a process that uses gravity to break and extract ore from large deposits. The exact method of ore removal used varies by the physical characteristics of the rock surrounding the metal, as well as the unique shape of the deposit. Deposits are often long and cylindrical, which is why they are known as veins. Silver Ore can be ...

    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. It involved mining the ore in underground galleries, washing the ores and smeltingit to produce the metal. Elaborate washing tables still exist at the site using rain w
