SIM CARD RECYCLING: How to recover gold from old SIM cards
Recovering gold from old SIM cards can be a profitable endeavor, as these devices often contain small amounts of gold that can be extracted and sold. Here is a step-by-step guide for recovering gold from SIM cards:
Start by disassembling the SIM card. This can typically be done by removing screws and separating the different components of the device.
Identify the parts of the device that contain gold. These are typically the connectors, switches, and other components that are used to make electrical connections.
Use a hammer or other tool to carefully break these components into smaller pieces. This will make it easier to extract the gold.
Use a hydrochloric acid solution to dissolve the gold. This can be done by mixing hydrochloric acid and nitric acid in a container and adding the small pieces of gold-bearing material to the solution. The acid will dissolve the gold, leaving behind other materials that can be discarded.
Filter the solution to remove any remaining solids. This can typically be done using filter paper or a coffee filter.
Collect the gold by adding a reducing agent to the solution. This will cause the gold to separate from the acid and form a solid precipitate that can be collected and dried.
Repeat the process as needed to extract all of the gold from the SIM card.
Recovering gold from SIM cards requires careful handling of hazardous chemicals and a thorough understanding of the process. It is important to follow all safety guidelines and use proper protective equipment when handling these materials.
