Electronics & Electrical
Contacts, switches, conductive pastes and printed circuits rely on silver’s unmatched conductivity.
Silver Mining
Silver mining: the working precious metal
Silver is prized as a precious metal, but most of it is put to work — in electronics, solar energy, medicine and industry. Here is how it is found, mined and recovered.
About Silver
A precious metal with an industrial heart
Silver has the highest electrical and thermal conductivity of any metal and the highest reflectivity of visible light. These properties make it indispensable to modern technology, alongside its long history in coinage, jewelry and silverware.
Unlike gold, a large share of silver demand is industrial. That links silver mining directly to the growth of electronics, electrification and renewable energy.
Silver Deposits
Where silver is found
Silver rarely occurs alone. Most of the world’s supply is recovered alongside other metals, which shapes how silver projects are evaluated and mined.
By-product silver
Most silver is recovered as a by-product of mining lead-zinc, copper and gold ores, so its supply depends partly on the economics of other metals.
Primary silver deposits
Some deposits, often epithermal veins, are mined principally for silver, with gold, lead or zinc as secondary products.
Silver minerals
Silver occurs as native silver, as the sulfide acanthite (argentite) and in complex sulfosalts, and is commonly hosted within galena.
Epithermal veins
Formed by hot fluids near the surface in volcanic settings; can carry high silver grades in quartz and carbonate veins.
Carbonate-replacement
Metal-rich fluids replace limestone, forming bodies rich in lead, zinc and silver.
Volcanogenic massive sulfides
Sea-floor deposits of copper, zinc and lead sulfides that frequently contain recoverable silver and gold.
Extraction Principles
Mining silver-bearing ore
Silver ore is mined with the same core methods used for other metals. Narrow, high-grade veins are typically mined underground using selective stoping, while large disseminated deposits may suit open-pit mining.
Because silver is often one of several payable metals, mine planning must balance the grades and recoveries of each one. A block that is marginal for silver alone may be valuable when its lead, zinc or gold content is included — making accurate multi-element modeling essential.
- Multi-element resource models and net smelter return calculations
- Selective underground methods for high-grade veins
- Grade control that tracks every payable metal
Processing Technologies
How silver is recovered
Comminution
Crushing and grinding liberate silver-bearing minerals from the host rock.
Flotation
Silver-rich sulfides such as galena are concentrated into lead or copper concentrates sold to smelters.
Cyanide leaching
In gold-silver ores, silver dissolves alongside gold and is recovered through Merrill-Crowe zinc precipitation or carbon.
Smelting & refining
Concentrates and precipitates are smelted, and silver is refined electrolytically to high purity.
Industrial Applications
Why the world needs silver
Solar Photovoltaics
Silver paste forms the conductive grid on most solar cells, linking silver demand to renewable energy growth.
Medical & Hygiene
Silver’s antimicrobial properties are used in wound dressings, coatings and medical devices.
Brazing & Soldering
Silver alloys create strong, conductive joints in HVAC, automotive and industrial equipment.
Catalysts
Silver catalysts are used in producing important industrial chemicals such as ethylene oxide.
Jewelry & Investment
Silverware, jewelry, coins and bars continue a tradition stretching back thousands of years.
Resource Efficiency
Making every tonne count
Resource efficiency in silver mining means recovering as much of every payable metal as practical. Improving flotation selectivity, optimizing grind size and reprocessing historical tailings can all lift recovery without disturbing new ground.
Silver is also highly recyclable. A responsible silver industry combines efficient primary production with support for recycling, so that mined metal stays in productive use for as long as possible.
- Higher recovery reduces ore mined per ounce
- Tailings reprocessing where technically and environmentally sound
- Energy and water intensity tracked per unit of metal
