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 …

I discussed your question with one of my process colleagues in order to get his input on separation of gold from black sands. It can be difficult to get a good separation as the black sands are quite dense. This is even more apparent when dealing with coarse sand and fine gold. I believe the i150 will be setup to run at a maximum speed of 50Hz.
