Silver processing Britannica

Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture. The silver was gradually converted to the elemental state in a very finely divided form, from which it was dissolved by the mercury. Periodically, the mercury was collected and distilled to recover the silver,

Silver mining Wikipedia

Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 C (1764 F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes. Ore treatment by mercury amalgamation, such as in the patio process or pan amalgamation was widely used through the 1800s, but is seldom used today.

How is Silver processed / made extracted & purified

14/12/2017 How is silver purified. In the lab of mining companies, technicians continuously ore samples to determine the grade. The term for the quantity of silver per Kg of ore. Then the workers heat the samples to 1093 degrees Celsius for about an hour to burn off the impurities. As after the burn off, the silver and other metals are left like Lead, Copper, Zinc, Cadmium and Selenium. Then the lab technicians treat the samples with the chemical that prevents silver

The Silver Extraction Process athens123

The Silver Extraction Process. 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

Extraction Of Silver Mineral Processing & Metallurgy

Very rich ore, containing 12 to 15 per cent, of silver, would require forty-eight hours leaching, and even then it would be necessary to subject the ore to a second leaching with the hyposulphite, with an intermediate roasting with green vitriol and salt; for, with the best work, if 95 per cent, are extracted, the tailings would still appear sufficiently rich for this, containing about 200

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
