About :

The video shows the process of recycling ceramic microcircuits from mobile phone boards in the amount of 42.5 grams. After removing the solder and removing foreign metals such as iron-nickel alloy, a rich gold-containing concentrate is obtained from which it is easy to extract gold with aqua regia (a mixture of hydrochloric acid with nitric acid) and restore gold from the solution with hydrazine salt, the resulting sediment can be easily melted and get - a gold bead.
