Silverbearing ore typically contains very little silver, with much higher percentages of copper and lead Specific minerals include argentite (Ag2S), chlorargyrite ("horn silver," AgCl), polybasite (Ag, Cu)16Sb2S11), and proustite (Ag3AsS3) Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively Silver is separated from this ore using a chemical process known as smelting To begin a new Silver mine, a system of multilayered crosscuts is made Each How is Silver Mined?

The abundance of silver in the Earth's crust is 008 parts per million, almost exactly the same as that of mercury It mostly occurs in sulfide ores, especially acanthite and argentite, Ag2S Argentite deposits sometimes also contain native silver when they occur in reducing environments, and when in contact with salt water they are converted to chlorargyrite (including horn silver), AgCl, which is prevalent in Chile and New South Wales Most other silver minerals are silver pnictides or The roasted ore contains chloride of silver, which does not dissolve in water, but generally there are also base chlorides in it, as Extraction Of Silver Mineral Processing & Metallurgy
Silver occurs uncombined, and in ores such as argentite and chlorargyrite (horn silver) However, it is mostly extracted from leadzinc, copper, gold and coppernickel ores as a byproduct of mining for these metals The Chemical Formula Ag Streak silver white Mohs Hardness 253 Crystal System Isometric Color Silver Luster Silver ore processing technology is used for recovering silver and associated Silver Processing Equipment, Process Flow, Cases
Silver refining is typically the final process in the production of highpurity silver suitable for sale in the market It is associated with purity and typically needs to meet a minimum of 999% The common extraction process is to enrich silver into lead, zinc, and copper concentrates, and then extract silver by smelting However, in the smelting Common Silver Extraction Methods Miningpedia
Silver is separated from this ore using a chemical process known as smelting To begin a new Silver mine, a system of multilayered crosscuts is made Each cut connects to a central shaft but is kept at a safe vertical distance to avoid collapses Openings called raises are dug to connect each levelOre processing Once removed from the mine, silvercontaining ore is crushed (comminution) into a fine powder to expose individual grains to chemical processingAs a byproduct of mining of lead and copper, Silver mining
Silver is a chemical element with the symbol Ag So the primary production of silver requires the smelting and then cupellation of argentiferous lead ores, a historically important process Lead melts at Silver occurs uncombined, and in ores such as argentite and chlorargyrite (horn silver) However, it is mostly extracted from leadzinc, copper, gold and coppernickel ores as a byproduct of mining for these metals The Silver Element information, properties and uses
The extraction of silver by the solving processes simple The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely After roasting, the ore Chemical Formula Ag Streak silver white Mohs Hardness 253 Crystal System Isometric Color Silver Luster Silver ore processing technology is used for recovering silver and associated Silver Processing Equipment, Process Flow, Cases
