Alkali-activated bricks made with mining waste iron ore tailings
Iron ore tailing (IOT) is a solid waste generated after the beneficiation process of iron ores. Further, due to the complex nature of ore, the amount of IOT generated varies from place to place. For instance, in Western Australia, the production of 1 ton of iron ore results in the generation of 2 tons of IOT [17].
