Is It Possible To Find Gold In Black Sand?
2020.7.22 Black sand is composed of a mix of iron-group metals: Hematite and Magnetite. It can often be found at the beach or in naturally occurring “placer deposits” of minerals found in river beds and streams, or veins of ore in rock faces. Black sand can also be a byproduct in operations that mine zinc, copper, and other metals.
