Knowra Silver mining Silver mining Silver mining is the extraction of silver-bearing ore from underground or surface deposits. Silver is recovered either as the main product or alongside metals such as lead, zinc, copper, and gold.
Mineral exploration : The search for mineral deposits using geological, geochemical, and geophysical evidence. Exploration identifies silver-bearing deposits before a mine is developed.
Silver : A lustrous, electrically conductive chemical element with symbol Ag and atomic number 47. Silver is the metal sought and recovered by mining.
Laurium : An ancient mining district in Attica, Greece, known for its silver-lead deposits. Laurium supplied silver that helped finance ancient Athens.
Flotation : A mineral-processing method that separates valuable particles from gangue by attaching them to air bubbles. Flotation concentrates silver-bearing sulfide minerals before smelting or leaching.
Silver standard : A monetary system in which a country's currency is defined by a fixed quantity of silver. Silver mining supplied metal used to back currencies and mint coinage.
Underground mining : The extraction of minerals through tunnels, shafts, and other workings beneath the surface. Many silver deposits are too deep or steeply inclined for surface mining.
Native silver : Naturally occurring metallic silver found in mineral deposits, sometimes alloyed with other elements. Some deposits contain silver in its uncombined metallic form.
Potosí : A Bolivian city founded near Cerro Rico, a major silver-mining mountain exploited under Spanish rule. Potosí became one of the largest and most consequential silver centers of the colonial era.
Lead smelting : The extraction of metallic lead from lead-bearing ores by high-temperature treatment. Silver commonly enters lead concentrates and is recovered during lead smelting and refining.
Spanish dollar : A widely circulated silver coin minted by the Spanish Empire, especially from the sixteenth through nineteenth centuries. Silver from American mines made the Spanish dollar a global trade currency.
