Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50 percent of mined silver today is obtained when processing other kinds of ore silver is separated from this ore using a chemical process known as smelting to begin a new silvermine, a system of multi-layered crosscuts are made.

Extraction. silver is extracted from the ore-argentite (\(ag_2s\)). 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. this reaction forms sodium argento cyanide \(na [ag(cn)_2]\).morethere

The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. during flotation, air is pumped through the ore-water slurry. platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.morethere
3. lead-bearing silver ores: these are silver ores containing 4 percent or more of lead. the silver comes mainly from the lead-silver ores of coeur d'alene, idaho, utah (chiefly park city and tintic), colorado (leadville and aspen). most of the output is obtained …morethere

Silver, as is described in classical, medieval and renaissance sources on pyrometalurgy. the lead reduction smelting process involves two-steps: a fusion of the ore material with lead in a carbon-rich environment, followed by the separation of silver from the lead in an oxygen-rich environment. periodmorethere
Silver can be found in nature in silver ore, silver ore is a mixture of other metals including silver. jewellery and silverware are traditionally made from sterling silver (standard silver), an alloy of 92.5% silver with 7.5% copper. in the us, only an alloy consisting of at least 92.5% fine silver can be marketed as "silver".morethere
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 …morethere
Treat ores containing as little as 1-3 g/ton gold . cyanidation processes are especially suitable for treatment of gold/silver-bearing sulphidic materials. gold cyanidation has been reported to involve the chemical reactions shown in eqs.
