    The remaining lead-gold-silver residue is treated by cupellation, a process in which the residue is heated to a high temperature (about 800 °C, or 1,450 °F) under strongly oxidizing conditions. The noble silver and gold remain in the elemental form, while the lead oxidizes and is removed. The gold and silver alloy thus produced is refined by the Moebius or Thum Balbach process. The residue

    How is Silver Mined APMEX®

    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
