— The required silver extraction process varies from the different mineral nature. The mineral extraction method usually used for independent silver ore centering on silver production is flotation extraction process.

— Mining. Open Pit Mining: If the silver is near the surface, large pits are dug to extract the ore. Underground Mining: For deeper deposits, underground tunnels and shafts are created. Blasting: Use explosives to break up the ore-bearing rock. Excavation: Extract the blasted material.
Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.
— The main sources of silver are mined as an ore of copper, copper-nickel, lead, and lead-zinc. In nature, silver is more likely to be found as a compound. In 2014, there was estimated to be 26,800 metric tons of fine silver available in the world.
— Silver ore refers to natural deposits of silver-containing minerals that are mined and processed to extract silver metal. Silver is a precious metal known for its lustrous appearance, high thermal and electrical conductivity, and various industrial, technological, and ornamental uses.
A typical ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony. After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony.
— The recovery of silver minerals occurring in a lead-zinc sulfide ore is efficiently accomplished using the above flowsheet. The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate.
— Silver is gauged by its "fineness," or the percentage of silver actually present in the metal or ore. fineness would be pure silver.
