![]() ![]() ![]() Exposure to these fumes is known to cause metal fume fever. ZINC Inhalation of zinc oxide fumes can occur when welding or cutting on zinc-coated metals. Congratulation you are about 50% finished. scoop these from the bucket into another container for future processing. Once you have pored off all the acid you will be left with a pile similar to what is in the picture. Simply Poor the contents of the two gallon bucket into the pickle jar using the coffee filters to catch any foils that are floating on the surface of the acid. ![]() or glass container large enough to contain waste acids. When this has been completed you will see a batch of gold foils floating in your now dark green acid. this works best at the temperatures of 80 - 90 F. This process can take up to 24 - 48 hours. At this point you should be wearing your safety gear because a few unfriendly fumes are being released. after the Peroxide has been added to your muratic acid the mixture should start to bubble, and the base metals should begin to dissolve. two parts muratic acid to one part hydrogen peroxide. To activate the solution you want to add your Hydrogen peroxide 3 - 5% solution in a 2 to 1 ratio. you want to keep your waste Acids to a minimum. Add enough muratic acid to cover your fingers about 1 cm above your materials. But first place your parts to be recovered inside your 1 gallon strainer bucket. First step, place your 1 gallon stainer bucket, into your 2 1/2 gallon wash bucket. Chemicals Muratic acid, and hydrogen peroxide. Tools 100 ML beaker, 1 gallon bucket, 2 1/2 gallon bucket. These metals can foul the reaction causing poor results. be sure to also remove any steel or iron parts attached. remove any visible capacitors transistors, or other components. After cleanly removing your plated sections of computer parts. Objective of this first chemical bath is to remove a large majority the base metals, Such as nickle, zinc and copper. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the base metals so when they are heated at high temperatures, the precious metals remain apart and the others react forming slags or other compounds *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore. THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS. ********************************** SEE HEALTH HAZARD ON STEP 6*************************************** **** a Side cautionary note, This process is not suitable to purify Panned Gold or KARAT (Gold Alloyed with silver.) This Guide is best suited for gold plated or pure gold object. No over the counter breather will protect you from these dangers Only lab grade isolated breathing systems can protect against metal vapors. These processes are DANGEROUS and put the user at the risk of inhaling vaporized metals. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. ![]()
