It is a leaching process for the extraction of gold or silver. Leaching is used to concentrate silver and gold ores. The ore containing native metal is treated with the dilute solutions of $text{ NaCN }$ or $text{ KCN }$ in the presence of atmospheric oxygen. The silver is leached as follows: [begin{matrix}
1990. During 1990, Arapahoe expended over $350,000 for exploration and development activities on the Horn Silver Mine properties. The work included continue preparation of topographic and aerial maps, drill site preparations, excavation of test stretches, drilling, geophysical exploration and sampling and the construction of the new road.
The extraction of silver chloride by leaching with aqueous ammonia solutions has not, until recently, been established as a large-scale commercial operation because of the concern of forming explosive silver compounds. Reference is sometimes made to fulminating silver compounds, silver azide, silver fulminate, or silver nitride as …
Horn Silver Mines, Inc. (Horn Silver) was incorporated under the laws of the state of Utah in 1971. In July, 1974, Horn Silver negotiated the acquisition of two mining contracts to mine and operate the old Horn Silver Mine properties consisting of 240 patented mining claims located near Frisco, Utah, in the San Francisco Mining District of Beaver County, …
Argentite, horn silver and pyrargyrite are important ores for the extraction of silver. Argentite in mineralogy, is cubic silver sulphide. It exists as a stable compound at temperatures greater than 179$^{0}text{C}$. However, upon cooling, argentite is converted or turns into its monoclinic form. This form is called acanthite.
This superficial silver ore is polished by desert wind and dust to the dull luster of a cow horn, hence the name "horn silver". A synonym of Chlorargyrite. An old name for chlorargyrite - from surface crusts of heavy gray silver chloride resulting from supergene enrichment and polished to the dull luster of a cow horn.
Ores mor Principles: The important ores of silver are. i) Argentite or silverglance, Ag 2 S. ii) Horn silver or chlorargyrite, AgCl. iii) Pyrargyrite or Ruby silver, Ag 2 S . Sb 2 S 3. The chief ore of silver is Argentite. The silver content in these ores is very small (about 1%). Silver is obtained to a small extent from the gold ores in the ...
Miriam B. Murphy History Blazer, January 1996. The story of the Horn Silver Mine, one of the great producers in Utah and American mining history, reads like pulp fiction: Two prospectors casually discover a rich ore body, a bankrupt financier promotes the venture, the boomtown of Frisco becomes one of the wildest mining camps in the West …
The Horn Silver Mine, which represents less than 1% of the overall acreage, shipped silver, gold, copper and lead ore from one breccia pipe and was one of the largest producers of the silver in the United States until 1930. During its production history the Horn Silver Mine produced 17 million ounces of silver, 25 thousand ounces of gold, 9 ...
Silver extraction process varies due to the different properties of silver ore. There are many kinds of silver minerals in the nature, among which those with production value include native silver, kustelite, phyargyrite, horn silver, dyscrasite and so on.

Crushing and Grinding: Crush and grind the ore into a fine powder to liberate silver particles. Concentration: Use froth flotation or gravity separation methods to concentrate the silver ore. Leaching: Apply chemical solutions, like cyanide or acid, to dissolve and extract silver from the concentrated ore. 5.
This is how we purify silver from argentite ( Ag2S A g 2 S) using sodium cyanide (NaCN) and zinc dust (Zn). -The commercial grade fine silver has a purity of silver of 99.9%. Silver with a purity of more than 99.99% can also be extracted. Note: Silver nitrate is used as an electrolyte to enrich the solution in silver ions for deposition at the ...
ii) Horn silver or chlorargyrite, AgCl . iii) Pyrargyrite or Ruby silver, Ag 2 S . Sb 2 S 3 . The chief ore of silver is Argentite. The silver content in these ores is very small (about 1%). Silver is obtained to a small extent from the gold ores in the kolar fields in Karnataka and in the Anantapur mines. Extraction of silver from the ...
Another story from the Milford News April 22 1937, sheds more light on the subject of how Frisco and particularly Horn Silver mine were discovered and started. "It was in Beaver county that the first metal mine in Utah was discovered. The find was made In 1854, seven years after the Mormon pioneers arrived.
Once the silver has been reduced to the desired size, it is moved through belts to a grinding process. Grinding. In the grinding, the silver enters some steel mills where it is converted into sludge, since it is constantly mixed with water for grinding. The addition of cyanide. Then to this silver mud is added cyanide.
Ultrasound-assisted extraction combined with electrothermal-atomic absorption spectrometry has been applied to the determination of silver and gold at μg g−1 levels in different environmental ...
But in 1885, it was the largest settlement in the southern Utah Territory. At the peak of the mining boom it had a population of around 4,000 people, at a time when less than 1,500 people lived in St. George. During the 1880s, prospectors extracted about 1.5 million troy ounces of silver from the Horn Silver Mine on a yearly basis.

Silver is a precious metal used since the ancient times to make money coins and high values objects. In its native form this precious metal occurs alloyed with Gold, Copper(II). Lead(II), or combined with other chemical elements in ores such as horn silver (AgCl), Argentite (Ag 2 S) [1]. Nowadays it is used in numerous fields of applications ...
The action of cyanide on the haloid compounds of silver, e.g., horn silver, differs from those already given in that oxygen does not appear as an indispensable auxiliary: AgCl + 2KCN = KAg(CN)2 + KCl ... where the presence of zinc lowers the extraction of the silver as much as 10% and in a less degree that of the gold. When zinc …

Horn silver is silver chloride (AgCl). On ancient silver coins, it is sometimes seen as a dull gray or black tenacious deposit. I'm unaware of any easy way to remove it without harming the underlying surface, although I have seen sodium thiosulfate recommended as a removal agent (soak the coin in a solution of sodium thiosulfate).
