  • 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 depositDec 27, 2011  You probably know that silver is a metal that’s mined and then somehow refined to form the pure coins and bars we trade as bullion, but would you like to know a little more about that process? We’ve found an excellent little YouTube excerpt by the Discovery Channel on the process of mining and refining silverExcellent Description of the Silver Mining Process Jan 28, 2018  Discover the mining and refining process of the precious metal of silver See a discussion on the history of this process including facts, figures, interesting and historical pictures, and the people and places involved Easy to read charts help to illustrate important concepts and definitionsSilver Mining and Refining EducationSilver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion Zinc reacts rapidly and completely with gold and silver, forming very insoluble compounds that float to the top of the bullion These are skimmed off and their zinc content recovered by vacuum retortingSilver processing BritannicaMINING AND PROCESSING : The Silver bearing ores are mined by either openpit or underground mining methods after which they are crushed and ground Despite of the existence of other technologies, this metal is mined through a process that uses gravity to break and extract its ores from large depositsSilver element extraction methods GREAT MINING
