Fire Metallurgy technology is the earliest technology to extract precious metals from electronic waste, and it is also the technology that is currently used mostly from waste appliances. The principle is to use high temperature to separate the non -metallic and metal objects in the waste appliances in the expensive metal components, and some non -metallic substances turn into a gas -out system; the other part is floating on the upper layer of metal melting materials. Gold and other precious metals form alloys with cheap metals in a melting state. After removing the surface of the surface, the melting alloy is injected into the corresponding mold to cool the corresponding mold, and then the precious metals such as gold are separated by refining or electrolytic processing. Separate each other. The most obvious feature of the fire method is simple craftsmanship, convenient operation, and high -precious metals (up to 90 %).
Pour the thick nitric acid into the cup, cut the circuit board, CPU, etc. and put it in the cup. Put the cup on the cup frame and heat it with alcohol lamps. Through filtering, sheets can be obtained. However, nitric acid is corrosive and easy to hurt. Be careful. The specific operation is very simple
Add the king water, let the gold ions be dissolved in the solution, then put it into the iron sheet, and replace it out of the gold
Personal extraction of gold is not recommended. The main thing to extract gold is the PCB gold finger part. Seeing your pictures, you may not buy some consumables. The 1 -ton gold finger extracts the gold and does not exceed 5 grams. Large environmental pollution
You can put it down and get the refined golden steel factory to plug.
