The chief ore of silver is argentite and silver is extracted from argentite by the hydrometallurgy process. Firstly, the silver ore is dissolved in cyanide solution to produce a soluble argentoplex from which the metal can be obtained by the reduction method. The different steps involved in the extraction of silver are as follows:
Silver mining is the resource extraction of silver by mining.. Silver is found in a native form very rarely as nuggets, but morebined 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

The mineral extraction method usually used for independent silver ore centering on silver production is flotation extraction process. Whileic and associated silver mines often uses ingle flotation method, flotation gravity separation method, and flotation cyanidation method, with flotation being the most important process.
In order to obtain the lustre and corrosion resistance of silver on other metals and alloys, silver electroplating is practiced. Cyanide based baths aremonly employed. Because silver has the highest electrical conductivity of all metals, it is used in alloyed form for electrical contacts.

Cyanide process, also called Macarthur forrest Process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest.

Electrolytic recovery is the most widely used silver recovery method for fixer solution and photographic processing solution. The silver is recovered from solution by electroplating it onto a cathode. A controlled, direct electrical current is passed between two electrodes suspended in the silver bearing solution.

Silver Mining Process. Silver is mined using a number of processes. One of themon processes of extracting silver metal for the ore is the heap leach or cyanide process. The process is most popular with many miners because it is low cost, especially when processing low grade ores.

Harraz Presentation Solution mining 02 Feb 16 Today, there are three methods used to produce dry salt based on the method of recovery Abu Khader, 2006. a Undergrounderground deposits through drilling and blasting whereby solid rock salt is removed.
There are four main mining methods: underground, open surface pit, placer, and in situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.
Cyanide process, also called Macarthur forrest Process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest.
Mining and concentrating Silver bearing ores are mined by open pit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30 to 40 fold concentration of mineral values is usually achieved.
06/04/2016· One of the earliest methods for extracting gold, salt cementation, was perfected through the Iron Age. When the Lydian Empire was standardizing the purity of the gold and silver they were using for the worlds earliest coinage, this was the method they relied on. When mined, goldmonly merged with silver as an alloy called electrum. Although primitive, salt cementation could separate
