Золото та срібло з роз'ємів РПГМ1: Результат афінажу

In this video, we will conduct a full cycle of refining contacts from Soviet GRPM1 connectors. The total weight of the material is 641 grams. We will go step by step from dirty scrap to pure precious metals: gold and silver. What you will see in the issue: Preparation: How to properly wash and degrease contacts before work. Chemical process: Dissolving the material in nitric acid and safety precautions when working with reagents. Unexpected find: Surprise in the package - gilded hairs that almost flew into the trash! Obtaining silver: Reduction of silver chloride using sugar syrup and caustic soda. Gold extraction: Working with "aqua regia" and the reduction of gold sponge, hydrazine. Final weighing: How much gold and silver was obtained from 641g of GRPM1? The result will amaze you! Refinement results: at the end of the video This process shows the real value of recycling radio components.
