process of producing silver from ore

Silver processing Britannica

Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture. The silver was gradually converted to the elemental state in a very finely divided form, from which it was dissolved by the mercury. Periodically,

Silver mining Wikipedia

Silver is also produced during the electrolytic refining of copper and by application of the Parkes process on lead metal obtained from lead ores that contain small amounts of silver. Commercial grade fine silver is at least 99.9 percent pure silver and purities greater than 99.999 percent are available.

How is Silver processed / made extracted & purified

14/12/2017· 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 Extraction Process athens123

The Silver Extraction Process. 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 silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore contains just a small percentage of

In cyanide extraction process of silver from argentite ore

The extraction of silver involves in cyanide process are:(i) Ag2S + 2CN- + O2 → 2[Ag(CN)2]- + SO2(ii) [Ag(CN)2]- + Zn → [Zn(CN)4]2- + AgThus, in equation (i) O2 act as oxidising agent (Oxidise sulphide to SO2) and in (ii) Zn act as reducing agent (reduce Ag+ to Ag).

PROCESS OF EXTRACTING GOLD AND SILVER FROM

The cement of copper, gold and silver separated to cathode is filtered separately and subjected to a leaching in sulphuric acid. The solution with 50-60 g/l Na 2 S 2 O 3.5H 2 O is adjusted to 3-4 g/l Cu and recycled in the ore leaching process. The gold and silver cement is melted in an alkaline-reducing medium to 1,200° C., obtaining the Au

9 Step Process for Discovering, Mining & Refining Gold

As you can see, the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot front-end investment and time. In the end though, we get these shiny coins and bars to enjoy. Gold miners too take special care to make the impact of mining for gold as light as possible. Reclaiming land to its previous natural state is the final and perhaps

Gold ore can then be physically extracted from the ground. Once the mine is tapped out, the mining company may be required (depending on the location) to restore and rehabilitate the site to pre-mining conditions, within reason. Mining companies may be required to monitor the ecology of the site after restoration. After authorities determine that the site has been successfully returned to a
