Things You'll Need
Instructions
Wear protective gloves, clothing, mask and goggles when handling hydrochloric acid. Open the windows and doors to provide ventilation in the work area.
Pour 1 cup of 25-percent hydrochloric acid solution into a heat-resistant, glass container.
Heat the solution using the "Simmer" setting on your stove. Do not boil the solution.
Remove the container from the stove. Place the cable pins into the solution. Completely submerge the cable pins in the solution.
Leave the cable pins in the solution for 12 hours. Check the cable pins every 2 hours. The hydrochloric acid dissolves all nongold material.
Pour 4 cups of vinegar into the glass container. The vinegar is a base and neutralizes the acid. Remove the gold from the container.
