  • How is Silver Mined APMEX®

    Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made. Each cut connects to a central shaft but is kept at a safe vertical distance to avoid collapses.

  • Silver mining Wikipedia

    Silver mining is the resource extraction of silver by mining. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with these or alloyed with other

  • Silver Mining and Refining Education

    Lead ores containing silver are extracted by cupellation,a process developed by the Chaldeans as early as 2,500 B.C. Today, the cupellation process involves heating crushed ore on a porous bed of bone ash until it melts. The lead and other impurities are absorbed into

  • Excellent Description of the Silver Mining Process

    You probably know that silver is a metal that’s mined and then somehow refined to form the pure coins and bars we trade as bullion, but would you like to know a little more about that process? We’ve found an excellent little YouTube excerpt by the Discovery Channel on the process of mining and refining silver. If you have 5 minutes, you

  • What Do Silver Miners Do? (with pictures) wiseGEEK

    Modern silver mining involves the use of explosives and heavy equipment. Miners may also be responsible for using a variety of physical and chemical processes to extract pure silver from silver ore. Shallow silver deposits can removed through strip mining. In a few very rare cases, precious metals may be found in such concentrations that they can be directly extracted from the earth in pure

  • Silver processing The metal and its alloys Britannica

    Between 25 and 40 percent of industrial silver is consumed in the production of the photosensitive chemicals silver chloride and silver bromide. These silver salts are prepared by adding sodium chloride or sodium bromide to a very pure solution of silver nitrate. The highly insoluble silver chloride or silver bromide then precipitates from solution. All processing takes place in the absence of any light.

  • Silver processing Britannica

    The noble silver and gold remain in the elemental form, while the lead oxidizes and is removed. The gold and silver alloy thus produced is refined by the Moebius or Thum Balbach process. The residue from silver refining is treated by affination or parting to concentrate the gold content, which is refined by the Wohlwill process. From zinc concentrates

  • The Silver Extraction Process athens123

    The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore contains just a small percentage of silver from 0.8% up

  • Silver Ore The Mining Processes that Transform Ore into

    The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a conducive alkaline conditions for the extractions. The ore is then stacked onto impermeable pads made of asphalt, rubber or plastic to ensure that there is

  • Patio process Wikipedia

    The patio process is a process for extracting silver from ore.The process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.

  • How silver is made material, making, history, used

    Silver mining in North America dates back to the eighteenth century. Around 1800, production began in the United States on the east coast and then moved west. The mining of silver was instrumental in the settlement of the state of Nevada. In 1994, Nevada was the largest producer of silver in the United States; Nevada mines produced 22.8 million troy ounces (709 million grams) of silver

  • Wastewater treatment in mining industry

    The origin of these effluents can be found in the distinct processes undertaken in mining, in addition to drainage from rainfall. Mining effluents can be caused by: Wash waters. Flow Process acids. Water leaching, flotation and concentration. Effluents from refining and gas scrubbers. Meanwhile, rain that infiltrates the tailings of the mine can also cause oxidation, hydrolysis, washing, etc
