Until a refining process has taken place with precious metal precipitants used to separate out the gold, for example, creating necklaces, rings and even bars from the ore is not possible. A number of different precious metal precipitants have been used through the years to extract the desired metal from different ores. Using Quicksilver / Mercury / Cyanide. Perhaps the most commonly used of
The extraction and stripping of gold showed satisfactory results at an organic/aqueous (O/A) ratio of 1:5 for extraction (~ ) and 5:1 for stripping (~ 92%), in the presence of decanol

Gold extraction Wikipedia
There are many different selective precipitants that can be used when refining gold. All will do the job well. However, your local supply house has one or two that they may favor. We recently developed Quadratic Precipitant to overcome many of the problems that refiners commonly experience. For whichever selective precipitant you decide to use, follow the instructions that accompany the
14/06/2010#0183;#32;The gold is fine, but you have not removed all of the base metals as indicated by the copper solids in the beaker. You must dissolve all of the base metals first with AP or nitric before moving forward. The best process to learn first is the AP reaction and a batch of fingers. Once you can crawl using this method, you can begin to walk using the AR method. In the meantime, read, read, read
