Black sand is a dark-colored sand composed mainly of heavy minerals like magnetite, ilmenite, and other iron-rich particles. It is commonly found on beaches, riverbeds, and volcanic regions. Its dense, coarse texture makes it heavier than regular sand. Black sand is often used in construction for making concrete and as an abrasive in sandblasting. It also has industrial applications in manufacturing and metal extraction due to its high mineral content. Additionally, black sand is popular in landscaping and decorative projects for its unique color and texture, adding contrast and aesthetic appeal to outdoor spaces.
