Early methods of silver mining - Golden State Mint Blog

Dec 28, 2011  Two early methods of mining silver were sluicing and hard-wall extraction. Sluicing involves assembling trenches in irrigation holes to filter out heavy metals from the mine. Unfortunately, sluicing is inefficient and ineffective method for obtaining silver. Hard-wall extraction is a basic silver mining method that is still used today, although ...

Silver element extraction methods - GREAT MINING

The Silver bearing ores are mined by either open-pit 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 deposits. This extraction method of removing the ore varies depending on the ...

Silver mining - Wikipedia

Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable by-product, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge
