2022.4.13 A gold spiral concentrator makes reducing the volume of black sand and extracting gold almost effortless. It is important to remember that gold spirals are not ideal for extracting gold from black sand. They will only work with alluvial deposits. If you know what type of gold-bearing material you have, it is always best to consult with a ...
