Advantages of extraction of silver from the ore

silver processing britannicasilver 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, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3a novel technique for silver extraction from silverin this study, a novel method for silver extraction from silver sulphide ore is described. the leaching process is based on the reaction between so 2 and h 2s, with thiosulphate as the complexing reagent. experimental materials and reagents the technical grade na 2s 2o 4,na 2so 3,na 2s 2o 3,nah 2po 4,h 3po 4 and nhdescribe role of nacn in extraction of silver from silver ore5 answers. extraction of silverrole of nacn or kcn = in the extraction of g and silver, the metal is leached with nacn or kcn, which is an oxidation reaction.during the process, ag is oxidised to ag+ .here m =ag or au.subsequent reaction with zn leads to formation of free metal.patio process overviewdevelopment of the patio processbasic elements of the patio procesoader historical significancesee alsofurther reading

the patio process is a process for extracting silver from ore. the process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by bartolomé de medina in pachuca, mexico, in 54. it replaced smelting as the primary method of extracting silver from ore at spanish colonies in the americas. although some knowledge of amalgamation techniques were likely known since the classical era, it was in the new world that it was first used on a large industrial scale. other amalga · text under ccbysa licensesilver mining overviewhistorysilver oresore processingsee also

silver mining is the extraction of the precious metal silver from the earth through excavation (i.e., mining).
silver is found in a native form very rarely as nuggets in placer deposits and veins. it is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (ag2s), chlorargyrite ("horn silver," agcl), and galena (a leadore often containing significant amounts of silver). as silver is often found in conjunction with these or alloyed with other metals such as g, it usually must · text under ccbysa licensename the chief ore of silver describe with chemicaljun 22, · argentite, which is a sulphide ore, is the chief source of silver. it is extracted by the process of leaching with a dilute solution of sodium cyanide. silver dissolves and forms a complex, argentocyanide. it is further treated with scrap zinc, which displaces silver from thethe extraction of g and silver from ore by the cyanide'fhe ore was sa.mpled and. this sample divided into eif';ht portions. the first part was crushed until all went. throu~h. a inch seive; the second part was crushed until all went. throu~h. a 30 inch seive, etc. the ore was then assayed for r and silver. after wei­ ~hin~,tbe~. and silver were parted. by. disso]vin~ the silver in
