The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.
Dec 14, 2017· How is silver extracted from its ore. ... The filter plate are treated with a zinc based chemical which attracts silver molecules. As the solution passes through, the plates trap particles containing silver forming a layer of black powder called silver precipitate. This precipitate is composed of approximately 50% of silver and 50% waste.
The silver are is dissolved in cyanide solution to form soluble argento cyanide complex from which metal is obtained by reduction with more electropositive. The different steps involved in extraction of silver are: a. Ore – Concentration: Argentite being sulphide ore and is concentrated by froth floatation process.

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as .
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 multilayered crosscuts are made.
sources is nearly onehalf of the total extracted. Extraction Processes. The high price of silver permits of poor ores being treated and the adoption of more costly methods. Hence chemical methods, preceded by careful mechanical preparation, are often followed. The treatment of silver ores proper may be divided intoAmalgamation processes.
