1. A method of producing a mixed metal compound comprising at least Mg having an aluminium content of less than 10000 ppm, having an average crystal size of less than 20 nm (200 Å) comprising the steps of: (a) combining a Mg (b) subjecting the slurry to mixing under conditions providing a power per unit volume of 0.03 to 1.6 kW/m (c) separating the mixed metal compound from the slurry, to obtain a crude product having a dry solid content of at least 10 wt % (d) drying the crude product either by (i) heating the crude product to a temperature of no greater than 150° C. and sufficient to provide a water evaporation rate of 0.05 to 1.5 kg water per hour per kg of dry product, or (ii) exposing the crude product to rapid drying at a water evaporation rate of 500 to 50000 kg water per hour per kg of dry product.
