pin foils with vinegar, peroxide, and salt | Gold Refining

While Vinegar, Salt, and Peroxide are effective at producing gold foils by removing brass, copper, or other base metals, further refining is still necessary. I should also note that the solution seems to have some difficulty with nickel, in that it takes longer to dissolve but does in fact dissolve it.

One of the main assets of the H2O cell is the use of "city" water. The residual chemicals is what allows the electrolysis to work. By adding salt to distilled water you alter the original cell into basically a saltwater cell. It will work but bringing the silver back to metallic silver will most likely require a different process.

How to Refine a Gold Smelt | Sciencing

In nature, gold nuggets are not pure gold. They are a combination of minerals, known as ore. The metal can be removed from the ore in a process known as smelting, in which the minerals are separated by melting point. Smelt gold is more pure than the original ore product, but can still contain impurities such as ...

Deep Guide To Gold Refining Process in Australia

Definition and Importance of Gold Refining. Gold refining is the process of purifying raw gold of its impurities and unwanted elements like silver, copper, zinc and nickel. The goal of refining is to produce gold that is at least 99.5% pure, if not higher. Achieving higher purity levels through refining gives gold several important advantages.
