摘要: According to the present invention there is provided a process for the agglomeration of titania slag particles comprising providing titania slag at a d50 particle 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 d50 particle size in the range from 106 μm to 1000 μm. The agglomerated particles have a (TiO2 and 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 TiO2 wherein such agglomerated titania slag particles are used.

摘要: This invention relates to a process of treating a zirconium containing product such as zircon. The process comprises providing an alkali fusion decomposed zircon product (AFDZ) formed from reading zircon with a source of alkali metal at elevated temperatures, and treating the AFDZ to form a solid containing hydrated zirconium oxide and/or hydrated zirconium basic carbonate (hereinafter referred to as the hydrated zirconium product). The process further comprises treating the solid hydrated zirconium product to obtain in situ formation of basic zirconium sulphate as a solid thereon. The invention also relates to such a process for producing zircon derived material suitable for pigments and to such a process to produce opacifier material. The invention also relates to products of such processes.
