    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 depositsDiscover 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 EducationSilverbearing 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 byproduct, 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 argeSilver mining Wikipedia
