Pure silver is seldom found outside of a jewelry store but impure silver is all around and those impurities can be refined out rather easily provided you take all the necessary precautions Refining silver without resorting to the use of a large smelting oven requires the use of nitric acid so safety is still as Jan 04 32 Since gold is present at the bottom of the reactivity series and least reactive among all metals so nitric acid even though being strong acid and oxidizing agent is not able to react with it but the mixture of nitric acid and hydochloric acid take

Acid based Refining Refining gold with ac The traditional method called aqua regia Latin for Royal Water dates back hundreds of years This method requires the use of both nitric and hydrochloric acids Due to the corrosive nature of nitric acid the fumes produced by this It is hard to tell what this is I m guessing the acetic acid dissolves the epoxy since that s what it do The gold is already metallic so it doesn t need to be extracted from ore

Refine Gold using Acid Peroxide method Now there are some mildly harsh chemicals used but no nitric acid You don t need AR Aqua Regia to dissolve gold or refine it You certainly don t need Mercury and Cyanide This is the easiest way that I know of to refine gold from scrap I ll be elaborating here in the near future as wellInquartation and Parting The technique mirrors part of the Fire Assay process used in the analysis assay of gold Inquartation involves initially diluting the gold in the refinable material to about 25 literally ‘quartering’ the gold by melting with the appropriate addition of copper or silver granulating the melt so as to generate a high surface area and then treating with nitric ac

Depending on how much silver you have to refine will depend on how many 5 gallon buckets you will need You can have larger buckets as well just as long as there is enough room for a reaction of bubbling and fuming you will get during this process You can refine silver using acid only or acid In addition to being a popular jewelry material gold is used in dentistry electronics drinks and food It has even been used by some as an alternative medicine for arthritis While gold doesn t have any taste or nutritional value it does add a touch of elegance to food and drinks

Any clean water without chlorine Chlorine mixed with nitric acid can dissolve gold Gold must be clean In order for mercury to attach itself Sometimes placer gold will be covered with a thin film of oil which will prevent the gold from being amalgamated unless the oil is cleaned off first PROCEDURE to Recover Gold with MercuryParting 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
