the extraction of metals an introduction This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis.
Sep 05, 2017· The silver ores are found along with gold ores in some parts of India. Extraction. Silver is extracted from the oreargentite (Ag 2 S). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution.

Silver is a precious metal located throughout the world in geological deposits. Colorado's state nickname is the "Silver State" due to the large deposits of silver ore found there. Silver is extracted from the ore by a smelting or leaching procedure. Here's how to identify silver ore.
Silver is extracted from the anode waste sludges of electrolytic copperrefining. Isotopes: Silver has 35 isotopes whose halflives are known, with mass numbers 94 to 128. Naturally occurring silver is a mixture of its two stable isotopes, 107 Ag and 109 Ag with natural abundances of % and % respectively.
Extraction of Silver by cyanide process and its uses. Silver also occurs both in combined state as well as in free state. The important ores of silver are: Argentite (Ag 2 S), Copper silver glance, Horn silver, Ruby silver. The silver ores are found along with gold ores in some parts of India.
When refining silver you want to make sure you do this outside where there is plenty of ventilation. Give yourself plenty of room in order to have a quicker dissolving reaction from the silver. Depending on how much silver you have to refine will depend on how many 5 gallon buckets you will need.
Silver: Silver is generally found in serpentine, trap, sandstone, limestone, shale, or porphyry rocks, the gangue being quartz, calc, fluorite, or silver ores are heavy, and many of them are sectile,, may be cut with the knife. Western men test for silver by heating the ore and dipping it into water.
used to extract gold from lowgrade ore deposits; crushed ore is placed on pads that have bottoms of asphalt or impervious plastic sheets, a solution of dilute cyanide is sprayed on the ore, the cyanide percolates down through the ore for several weeks to months and leeches out the gold, now a solution, the gold drains off the pad, the gold is pumped to a recovery plant where the gold is ...
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 ...

Types of iron ore: Hematite ore. Hematite ore is a directshipping ore with naturally high iron content. Because of its high iron content, hematite ore must undergo only a simple crushing ...
Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
