Iron | Geoscience Australia
Iron and some alloys of iron are also magnetic. Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.

Recovery of iron from cyanide tailings with reduction roasting–water
Highlights Using reduction roasting–water leaching–magnetic separation method, the recovery of iron from cyanide tailings was optimized. The recovery of iron was highly depended on the water-leaching process after reduction roasting. The results suggest that the method can be effectively used for iron recovery, and the grade of magnetic …
