    Producing sodium silicate powder from iron ore tailings ...

    This study evaluated the use of iron ore tailings (IOT) as a source of silica (SiO 2) to produce an alternative form of sodium silicate (SS) for use as an activator in one-part geopolymer binders. The novel SS was produced in a mechano-thermo-chemical process for mixing IOT with sodium hydroxide (NaOH).
