ABSTRACT:
According to the present invention there is provided a process for the agglomeration of titania slag particles comprising providing titania slag at a d50particle size of below 106 μm; mixing the slag particles with an organic binder; and agglomerating the mixture of the slag particles and organic binder into agglomerated particles with a d50particle size in the range from 106 μm to 1000 μm. The agglomerated particles have a (TiO2and FeO)/C mass ratio of more than 3.4. The invention also relates to such agglomated slag particles and a chloride process for the production of TiO2wherein such agglomerated titania slag particles are used.
