copper mining and extraction sulfide oresmetals are often found as compounds in ores. an ore is a rock or mineral that has enough metal in it to make it worth extracting. mining copper about 0 s ago the uk was an important world source of copper and tin and there were mines in cornwall and devon.the strange case of the earliest silver extraction byfeb 27, 07· in medieval europe, bone ash was commonly used for lining cupellation hearths (3), because it absorbs litharge but does not react with it. using bone ash in the cupellation process makes it possible both to extract silver and to recover desilvered leadcited by 23silver mining sep , 06· the principal sources of silver are copper, copper nickel, g, lead, and lead zinc ores obtained from canada, mexico, poland, peru, bolivia, australia and the united states.history · silver ores · ore processing · parkes process · cerro rico · silver mining in the united statessources of beryllium metal and extraction locationstoday, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a watersoluble sulfate. bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.silver silver is a chemical element with the symbol ag (from the latin argentum, derived from the protoindoeuropean herǵ "shiny" or "white") and atomic number 47. a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. the metal is found in the earth's crust in the pure, free elemental form ("native silvergroup group extraction of metals methods of extraction of metalssuch sources are called ores. also read bauxite; extraction of metals. the process of extracting metal ores buried deep underground is called mining. the metal ores are found in the earths crust in varying abundance. the extraction of metals from oresrecovery of silver, g, and lead from a complex sulfidegsilver ores. a procedure to extract silver from sulfide ores with fec was patented by hey in 22 (6). considera ble work was completed bywong (7) to re cover lead from a galena concentrate with a combined fecnacl leach solution. because both lead and silver were solu bilized, silver recovery from highsilvercited by 4sources of error in a lab experiment? answerssep , · it really depends on the type of experiment performed. but in any given experiment, there could be hundreds of variables that, when inadvertently changed, can affect the results.
