For some of the base metals it takes a little extra Oxygen to get this done so adding Hydrogen Peroxide andor using a fish tank bubbler will provide extra oxygen and help things along Next you actually dissolve the gold thats right make Gold Salt Auric Chloride and filter that Replace the gold in that salt with sodium and Voila

hi and nice post of the electronic gold im bin doing for some time and have alot what use are hydrogen peroxide and hydrochloric acid5050 great mix but wonder how pure are the gold fingers after that do you know that i have plan to grind all to powrder them pan it im an gold digger as well then put it in acid bath regards johnnyMore Detail +

Hydrogen peroxide is the bleaching agent for the treatment of natural and synthetic fibers cotton wool silk linen rayon The use of hydrogen peroxide allows not only a high degree of brightness but also preserves the mechanical properties of the fibers Similar to pulp bleaching this process takes place in an alkaline environmentMore Detail +
The numerous hydrogen peroxide uses and benefits make it a great allnatural and safe chemical to use in all aspects of your life 60 fantastic uses and benefits of hydrogen peroxide From uses for hair teeth skin or ear up to health benefits when used as mouthwash or foot soakMore Detail +
Hydrogen peroxide H2O2 is a very pale blue liquid which appears colourless in a dilute solution slightly more viscous than water It is a weak acid It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper but has also found use as a disinfectant and as an oxidizer HydrogenMore Detail +
Hydrogen peroxide is used in the mining industry for the extraction of precious metals such as gold platinum and palladium Gold extraction from natural sources including gold rocks and gold ores can be done by leaching the gold concentrate or crushed gold rocks in a solution of hydrogen peroxide and hydrochloric acidMore Detail +
Already 75 years ago it was found in batch experiments that hydrogen peroxide increases the gold extraction rate but the results were not convincing enough It was also found that hydrogen peroxide attacks the cyanide a process which was developed over the last 10 years by Degussa to destroy cyanide in gold mine effluentsMore Detail +
Hydrogen peroxide could also be used for lowpressure oxidation but the economics are quite unfavorable for most ores although one notable exception is Pine Creek Australia where hydrogen peroxide has been used during gold leaching principally for sulfide mineral oxidationMore Detail +
Gold cyanidation using hydrogen peroxide as an oxidising agent has been studied by performing kinetic experiments open circuit potential measurements and voltammetry Small amounts of hydrogen peroxide make the cyanidation rate lower than that in conventional cyanidation but higher amounts can make the cyanidation rate doubleMore Detail +
