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

Pure silver is rather soft and its traditionally combined with one or more metals to give it strength and hardness. The silver used in the jewelry is sterling silver. As sterling is composed of 92.5% silver and 7.5% alloy. The alloy is usually copper or copper combined with other metals. How is silver extracted from its ore

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.

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," Ag Cl ), and galena (a lead ore often containing significant amounts of silver).

Chlorargyrite, despite being an important ore of silver, is not well-represented in collections. This is because of its general lack of aesthetics, with the bulk of mined material being processed for the extraction of its silver content. Formerly called Cerargyrite, Chlorargyrite is the currently accepted name of this mineral today.

5.2 x 2.8 x 2.0 cm. Chlorargyrite (an important silver chloride ore) and coronodite (Pb-Mn oxide) combination specimens are very uncommon from the famous Broken Hill deposit.

An ore is usually contaminated with earthy or undesired materials known as gangue. Native ores contain the metal in the free state. Silver, gold and platinum occur as native ores. ... Chlorargyrite (Horn silver) AgCl. Metallurgy: The scientific and technological process used for the extraction/isolation of the metal from its ore.

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 the bone ash, and the molten silver is drawn off.

Silver and gold are extracted by the cyanide process (Mac Arthur - Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 - 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.

The extreme insolubility of the silver halides (chlorargyrite, embolite, bromargyrite, iodargyrite) over broad pH and climatic ranges, besides efficient silver fixation as native silver, argentojarosite, or silver-bearing manganese oxides under the appropriate chemical conditions, explains the metal's relative supergene immobility.

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).

Metallic silver dissolves anodically in aqueous cyanide solution, in a similar manner to gold, in line with the following reaction (Marsden and House, 1992): (1) Ag(CN) 2 − +e=Ag+2CN − (E°=−0.31 V) The Eh–pH diagram for the Ag–CN–H 2 O system, given in Fig. 1, shows the region of predominance of Ag(CN) 2 − and indicates that insoluble silver cyanide, AgCN, is formed at low pH.

The chlorargyrite forms on top of silver ore veins that have been subjected to weathering. The silver ore vein is often of such a concentration that it would not be a very profitable ore body were it not for a process called supergene enrichment. Supergene enrichment occurs when certain metals are leached out of slightly soluble minerals by ...

The common gold-silver ore extraction process has the following types: 1. Flotation + Flotation concentrate cyanidation. The sulfide ore containing gold, silver and quartz veins is subjected to flotation process to obtain a small amount of concentrate, which is then sent to cyanidation process. Compared with all-sliming cyanidation process, the ...

Chlorargyrite is a silver-chloride (AgCl) mineral and occurs naturally as a secondary mineral formed during the oxidation process of silver deposits. The mineral was first reported in 1877 from Broken Hill District, New South Wales, Australia, and named from the Greek, "chloros" for "pale green" and Latin for silver, "argentums."

Processing. At the surface, the ore is subjected to additional crushing and fine grinding. A flotation process is used to separate the silver-bearing galena and tetrahedrite from other ore minerals and waste rock particles (tailings) to form mineral concentrates. Development of the flotation process occurred in the early days of mining at ...

Silver can be found and mined from the Earth's crust in its purest form, known as native silver. It is often found in alloys with metals such as gold and copper, and in minerals, such as chlorargyrite and argentite. However, silver is more commonly produced during the process of refining of other metals, such as copper, lead, zinc and gold.
