Silver Ore - The Mining Processes that Transform Ore into Bullion .Dec 18, 2016 . Silver is quite different from gold because it is nearly always found within ores that require specialized mining techniques to extract. Silver ore is one of the most important resources on Earth. After processing and refining silver is used for countless industrial uses today.methods of processing silver ore,Silver processing | BritannicaSilver-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.
