silver processing britannicasilver is removed by the parkes process, which consists of adding zinc to the molten lead bullion. zinc reacts rapidly and completely with g and silver, forming very insoluble compounds that float to the top of the bullion. these are skimmed off and their zinc content recovered by vacuum retorting.silver extraction from waste water of silver clusterthis paper presents the different methods of silver extraction from waste water. the processes used are chemical as well as electrical. electrolysis process is used to get silver. keywords silver extraction, electrolysis process, volhards method and mohrs method. 1. introduction the present method of extracting silver ishow silver is made material, making, history, usedin this process, ore was heated with rock salt, producing silver chloride, which was leached out with sodium hyposulfite. today, there are several processes used to extract silver from ores. a method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a lowcost way of processing lowergradesilver ore the mining processes that transform ore intothe main sources and uses for silvercharacteristics of silversilver mining processsilver mining around the worldsilver production in the u.s.silver is mined using a number of processes. one of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process. the process is most popular with many miners because it is low cost, especially when processing lowgrade ores. to use the cyanide process the silver being in the ore should have smaller particles, should be able to react with the cyanide solution, the silver should be free from sulfide minerals and other foreign substances. the following are the major steps incommon silver extraction methods miningpedia rows· jun , · the required silver extraction process varies from the different mineral nature. the mineralsilver ore characteristics extraction methods coarse particles (> 0.1 ~ 0.2 gravity separation coarse particles (> 0.1 ~ 0.2 cyanidation native silver and native alloy cyanidation see all rows on .miningpedia us4728402a electrolytic silver refining process googlean electrolytic silver refining process in which crude silver is anodically dissolved and refined silver is cathodically deposited and at the same time accompanying metals are selectively extracted from the spent electrolyte and separately cathodically deposited after having been transferred into an aqueous phase and the regenerated electrolyte stripped of accompanying metals is recycled tohow is silver mined apmexsilver also occurs alongside lead, copper and zinc ores, which is why nearly 50% 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 silver mine, a system of multilayered crosscuts are made.
