Extracting Gold From Used Electrical Contactors gold plated pins

@MakeGold use of hazardous chemicals and specialized knowledge and equipment. It is not recommended for amateur or inexperienced individuals. Improper handling of these chemicals can result in serious injury or harm to the environment. Here is a general outline of the process: Grind the pins into small pieces to increase their surface area. Place the pieces in a container with a strong acid, such as muriatic or hydrochloric acid, which will dissolve the metal and leave the gold. Allow the mixture to sit for a few hours, stirring occasionally. Neutralize the solution with baking soda to stop the reaction and prevent the release of toxic fumes. Filter the solution to remove any impurities and solid residue. Use a process like electroplating or smelting to isolate the gold from the solution and purify it. Keep in mind that this process involves handling hazardous chemicals and generating toxic fumes, so it should only be performed in a well-ventilated area with proper protective e
