How to get gold flakes out of a circuit board?
A week has passed and it is time to collect your gold flakes and dust from your cleaned fingers and circuit boards, after a week the acid darkens and with a stir the flakes of gold can be seen floating around in the pot.#N#Pouring the acid into a coffee filter the acid passes through the filter leaving the gold behind, save the acid do not dump it down the drain.#N#Next dump the remaining fingers and circuit boards into a deep plastic tray and add water, sort out the cleaned of gold parts, put the cleaned parts in the waist and save the un-cleaned parts for re-dipping.#N#After you have sorted the circuit board parts pour the water off through the coffee filter and flush with methyl hydrate to clean. Since the methyl hydrate is 99.9% methyl alcohol it cleans and dries the gold flakes better and faster than water, water will cling to the gold flakes and give you a false weight.
How to recover gold from a gold flakes?
There are basically two methods of melting gold flakes and dust to recover gold available to the average person, the mercury method called Gold-Mercury Amalgam with its obviously toxic by-products and the Borax Method.#N#I do not recommend the mercury method it works but it is extremely toxic for generations.#N#The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ?C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery increases.
