Gold can be separated from other metals at home using a method called gold panning. This method takes advantage of the high density of gold, which allows it to sink to the bottom when mixed with water and other materials. Here's a simple step-by-step guide: 1. Fill a pan with sand and gravel that potentially contains gold. 2. Submerge the pan in …
