There is described a novel process for pelletizing clay containing aluminumous ore comprising the steps of: a. crushing the clay to within an appropriate size range; b. blending the crushed clay with water to achieve a closely defined moisture content; c. pelletizing the clay in a suitable apparatus to provide clay pellets of predetermined size; d. rolling the pellets for a period of time sufficient to round the edges, corners, etc. and to produce a relatively hard, abrasive resistant surface; and e. drying and calcining the pellets at a temperature within the range of from about 1100 DEG to about 1500 DEG F.
