Magnetite is a common heavy mineral in sand. This rock is a metamorphosed sand deposit which seems to be very rich in heavy minerals magnetite (black) and garnet (red). Varanger Peninsula, Northern Norway. Width of sample 18 cm.

However, sand that does not contain these compounds won't be magnetic. It's easy to tell what sand will be magnetic and what sand won't be magnetic by looking at it. Since magnesite is dark in color, you can assume black sand is magnetic. When black sand is found in areas that don't have volcanoes, it is usually in a stream or riverbed.

Black sand beaches are black because many volcanic minerals and rocks are dark-colored. Common rock types of volcanic islands are basalt (black when fresh), andesite (usually dark gray) and volcanic glass (often black in color). The minerals that give black color to these rocks are predominantly pyroxenes (mostly augite), amphiboles (mostly ...

Black sand is beach deposits that come from the headwaters of the Nile, which are rich in heavy minerals. It is named so because of its dark color as it contains a high concentration of iron. The most notable minerals found in black sand are ilmenite, zircon, magnetite, rutile, garnet, and monazite, which contains radioactive materials.

This part of the sand separates itself when it meets a magnet, so it's appropriately called magnetite.

Experimental work was carried out to study new fine aggregate shielding construction materials, namely black sand (BS). The BS effect on the mechanical, durability, and shielding characteristics of heavyweight high-performance concrete (HWHPC) was evaluated. ...
