Dec 31, 2000 · Abstract. WOS: A novel technique for silver extraction from Ag2S is described. The mettled utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved.
The ManufacturingProcess. Silver was first obtained in sixteenthcentury Mexico by a method called the patio process. It involved mixing silver ore, salt, copper sulphide, and water. The resultant silver chloride was then picked up by adding mercury. This inefficient .
Silver refining is typically the final process in the production of high purity silver suitable for sale in the market. It is associated with purity and typically needs to meet a minimum of % purity and in most cases % purity and in some cases % purity depending on the enduse. The silver can be sold in many different forms in ...

Dec 19, 2011 · Besides, the sulfide ions can be tested by adding with sodium nitroprusside reagent. The formation of purple or violet colour shows the presence of sulfide ion. Silver ion reagent can be used to confirm the presence of halide ions in the compound. The formation of precipitate between halide ion and silver ion as shows below:
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 the extraction of silver are: a. Ore – Concentration: Argentite being sulphide ore and is concentrated by froth flotation process.
Apr 24, 2017 · Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves ...
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 silverbearing and is known as Argentiferous Galenite (formula ()S ) and the lead obtained from this ore ...
Answer (1 of 3): Dissolve the ore in an acid other than hydrochloric. Once dissolved, add HCl or NaCl or any other chloride. Once enough chloride is added, a white silver chloride precipitate will form. However, chlorides of Pb^{++} and Hg^+ are also insoluble in water and acids solutions. The ma...
Electrum with a high silver content may give poor gold extraction due to tarnishing of the silver. Iron sulphide ores and arsenic sulphide ores: Iron sulphide ores and arsenic sulphide ores host different proportions of nonrefractory and refractory gold.
The smelting process consists in the formation of an alloy of gold with silver and lead, and is similar to that employed in extracting silver. It is applicable to ores rich in silver, and also to refractory ores containing arsenic and antimony, Inquire Now; Refining Gold Jewelry Scraps Ganoksin Jewelry
