PROCESS FOR THE MANUFACTURE OF FINE PARTICLE SIZE METAL OXIDES ABSTRACT OF INVENTION Metal oxides are prepared by reacting the corresponding gaseous metal chloride with oxygen, or oxygen-containing gas, at elevated temperature to form metal oxide-burdened reaction gases at elevated pressure, the metal oxide-burdened reaction gases being thereafter conducted into and through successive gas cooling and metal oxide separating zones, respectively, and feeding the metal oxide-free gases, while still at elevated pressure, into a chlorinating zone to chlorinate a metal bearing ore and form additional gaseous metal chloride.
