Blast furnace slag is expected to be applied for a mineral carbonation process. This process produces a new waste of undissolved residue by acid treatment. The waste is mainly consists of SiO2, and the development of a utilization system for the waste would be desirable. In the current study, the undissolved residue was successfully used as raw material for the synthesis of allophane, which is a functional material as pollutants adsorbent.
