Золоті волосинки: афінаж безкорпусних мікросхем та несподіваний вихід золота

In this video, we will conduct an exciting experiment on refining an unusual material — caseless microcircuits. At first glance, they look like an ordinary bundle of copper wires, but is it really so? Together, we will check these "golden hairs" for authenticity using nitric acid, going all the way from dissolution in "aqua regia" to the restoration of pure gold with hydrazine and the final melting. What you will see in the video: Gold test: Checking the material's reaction to hot nitric acid. Refinement process: Step-by-step dissolution of microassemblies and filtration. Result: Weighing the obtained gold and evaluating its sample. Bonus: My faithful assistant is a cat who is always there during work! Refinement results: From the starting material, we obtained 0.28 g of gold. This confirms that caseless microcircuits are an extremely rich and profitable raw material for refining (at least 950 fineness).
