Gold parting is the separating of gold from silver.gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. over the centuries special means of separation have been invented. Parting of copper and gold. if parting depended on the formula alone, assuming that the alloying metal was dissolved by nitric acid, then copper should do as well as zinc, since the atomic weights are nearly equal. in order to determine this an alloy of 10.008 of gold and 10.080 of copper was made and placed in 1 of nitric to 2 of water and boiled. Parting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary. After removing the gold, you can convert the silver chloride back into silver, giving you two separate, purified samples of precious metals. of course, modern metal refining has come up with more effective and efficient methods of gold parting, such as the miller process and the wohlwill process. thankfully, neither process requires urine.

Gold annealing crucibles and parting flasks are the key instruments to achieve this. the reason for using nitric acid, is that silver is soluble in it but gold is not. however, to ensure that no silver is secluded into the gold, and therefore protected from being dissolved, it is first necessary to laminate the bead into a cornet.
