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,
Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. 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.
Two different ore bearing sulfide assemblages are found at the Galena, a silver-copper ore and a silver-lead ore. Grades of the silver-copper veins range from a few ounces of silver to over a thousand ounces of silver per ton and since 1953 have averaged over 22 ounces per ton.
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.
Following dilution of this aqueous solution and adjustment of pH, silver is again extracted into chloroform as the dithizonate, and determined absorptiometrically. Analyses of a number of galena ore samples showed a precision of within 3% for a silver content ranging from 0.03 to n AW- -.A IU.
Galena also was a major mineral of the zinc-lead mines of the tri-state district around Joplin in southwestern Missouri and the adjoining areas of Kansas and Oklahoma. Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana.

Feb 26, 1997· I have a source of Galena (lead ore: PbS + impurities), actually I live over an old silver-lead mine - or so they say. Now I fancy: 1. assaying for the silver content; 2. If there is sufficient silver have a go at extracting some of the silver as silver metal. Q. How do I go about extracting silver?
Lead and zinc ores (usually sphalerite, ZnS) often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation, a succession of stages each delivering a greater concentration ...
Galena can also be used in alloy reactions requiring silver-bearing ore. Because these reactions treat the galena nugget as the equivalent of 4 silver bars, the resulting alloy will show a roughly 30% increase in value over smelting the galena separately. Galena is also magma-safe, but just barely. Since galena is a mid-value ore, however, you ...

Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its importance ...
Aug 16, 2018· Silver from Galena Extraction After reading a forum post from user Udary titled 'A use for Galena', he mentions a way to extract silver from the currently unused ore Galena.
