Common Silver Extraction Methods - Mining-pedia

1. Use cyanide-free or micro-cyanide process. Silver flotation process with no or less use of cyanide, which inhibits silver minerals or carrier minerals, is beneficial to the recovery of associated silver and has received extensive attention. More than 60% of lead-zinc-copper mines have applied this method and achieved good results. 2.

The cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.

Silver Ore - The Mining Processes that Transform Ore into ...

18/12/2016· Silver Mining Process . Silver is mined using a number of processes. One of the most common 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. To use the cyanide process the silver being in the ore should have smaller particles, should be …

Extraction of silver from Argentite | Reference Notes ...

The chief are of silver is argentite and silver is extracted by hydrometallurgy process. 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 – …

Silver Gold Recovery Flotation Process

17/03/2017· The cyanide-agitation process is usually the most suitable method of extraction, but it often necessitates grinding to a fine size to release the gold and silver. Should it be possible to obtain a good recovery by flotation in a concentrate carrying most of the pyrite or other sulphide minerals, it may prove more economical to adopt this method, regrinding only the comparatively small bulk of ...

The Silver Extraction Process - athens123.com

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 silver - from 0.8% up ...
