Silver mining is the resource extraction of silver by mining Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver .
How lead is made - material, used, processing, product ,
Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteri Besides the ore itself, only a few raw materials are necessary for the refining of lead
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use
How was silver refined in the roman and Iron Age ,
By far the largest sources of silver in the ancient world were lead ores, but until metallurgists discovered how to smelt them very little silver was available to artisans To extract their precious prize, smelters first reduced the ore to lead containing small quantities of silver
Usually, lead is found in conjunction with other metals such as silver and zinc Lead materials are mined as a by product of these other more valuable metals Extracting the lead materials from the ore is a multi-step process First the lead ore is ground into small particles that are less than 01mm, giving the ore a texture similar to table salt
Extraction of Silver by cyanide process and its us 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
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

Silver Ore - The Mining Processes that Transform Ore into ,
Dec 18, 2016· In many places, silver ore is often found in combination with other ores containing other commercially viable minerals such as copper, lead or gold When silver is a byproduct of processing these other minerals then a different method has to be used to extract the silver ore For example is silver is found in ore containing zinc a method known .
Lead Ore / Lead Concentrate Smelting, Manufacturing ,
Lead ores are usually associated with other metals, particularly silver which can be mined at the same time – and zinc, which can cause problems during smelting The Sulfide Mineral, Galena, a Lead sulfide, PbS, is the most important ore mineral of Lead It can contain 86% Lead
Silver processing, preparation of the ore for use in various products Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen The lustre of the pure metal is due to its electron configuration.
The cupellation process was used to assay silver as well as extract it Smelt the lead/silver ore Continue to heat with zinc (at about 10 of lead to 1 of scrap zinc) Skim off the zinc (if you let the whole lot cool together, you may be able to liberate the zinc using a hammer - ,
