My fear is that leaching will occur over time and the bath will have to be treated for silver impuriti Any.Silver A native element, mineral, alloy, and byproductSilver is a soft, white metal that usually occurs in nature in one of four forms 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals Most of the silver produced today is a product of the fourth type of occurrence.Sulfides, Selenides and Tellurides rebellious andWell, sulfides, selenides and tellurides are simply minerals which contain sulfur, selenium, and tellurium combined with some metal Unusually this is the metal we are interested in, but sometimes other valuable metals can be mixed in as trace elements , preventing the cyanide from leaching out the gold and silver.Aurorra Gold Mining Non Cyanide LeachingCLS as a gold and silver leach was designed to leach concentrates, but that is not the best purpose to which CLS can be addressed All ores must be evaluated after testing to determine economic feasibility for direct leaching with CLS Many ores will not prove to be rich enough for leaching with CLS, even though it is successful when used.EP0020826A1The filtered solution was found to contain 2724 g of silver, 2156 g of selenium, and 106 g of tellurium, together with the other impurities; this is equivalent to a 961%, 97%, and 76% leaching rate for silver, selenium, and tellurium respectively.

Silver cyanide

Silver cyanide is the chemical compound with the formula AgCN This white solid forms upon treatment of solutions containing Ag + with cyanide This precipitation step is used in some schemes to recover silver from solution Silver cyanide is used in silver plating Structure Its structure consist.
