  • How to Separate Gold and Black Sands - Gravity

    2021-12-25 · 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.
