Iron sand (see photo to the left) is a special type of sand that's rich in the metal iron. While most sand contains at least some trace of iron, iron sand has a significantly larger concentration. As a result, it has a distinct blackish-gray color, which is in stark contrast to the white-yellow color of regular sand.

The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screw-fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (typically approx. 700 °C) and high pressing forces.
