I see workers who specialize in the work. Use cement mixed with water to resmelt the gold alloy. I’m still wondering what this procedure is for. Or just reduce the size of the metal to a smaller size. To make it easier for nitric acid to handle these metals. and left only gold
The metal will be melted. and was poured into the water to get a smaller size as needed
Use nitric acid mixed with water 1 to 2. Boil to get rid of these metals. and will only be left with gold as an interesting step
