Invention patent for "Process for preparation of raw material, minimizing the grain size degradation of anatase ore". The process basically consists of the removal of the minerals more resistant to comminution than anatase, before its grinding stage. The process includes the wet disaggregation of the ore, screening and crushing of the ore originating in the disaggregation step, classification, screening of the coarse product of the classification, magnetic concentration, grinding for liberation of anatase and desliming followed by thickening, filtering and drying of the material. |
