· How To Use Aqua Regia To Purify Gold. Place your gold or finely powdered ore in a Pyrex container breaker. Mix 1 part nitric acid to 3 parts hydrochloric acid in a separate glass or plastic container. When mixing the acids together, use great caution! Add the acid mixture, very slowly, to the Pyrex container or beaker containing the ore.
Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. These processes are DANGEROUS and.

Step 9. Mix a refining solution. Although you have recovered the gold from the electronics scrap, it may not be pure gold. It may be 12k or 18k gold, so now we will refine it to be pure 24k fine gold. Take a second beaker and pour it half full of Aqua Regina.
Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and postconsumer value chain.

Pure scrap gold only requires melting, so perhaps you wish to recover gold from scrap computers, etc. The highly hazardous liquids that dissolve gold also dissolve other metal present. 12 V will plate out all the metals together (Ag, Cu, Fe, Ni, Pb, Sb, Sn, Zn, etc.) and dissociate water into an explosive mixture of hydrogen and hydrogen.
These gold components are, despite appearances, not "ripe" with gold. Yes, refining gold fingers is easier than refining ore, but that doesn't mean it is "full" of gold. It will take hundreds of pounds of computers to get even close to an ounce of gold.
250 g/t for computer circuit boards, this "urban mine" is significantly richer than what is available in primary ores. However, the "mineralogy" in scrap products is much different than in the conventional ores in a gold mine: Up to 60 different elements are closely interlinked in complex assemblies and
