ABSTRACT:
Nodule fines, formed by abrasion of an electric furnace feed material of phosphate shale nodules, are utilized by mixing a recycle stream of the nodule fines with fresh phosphate in the presence of phosphoric acid prior to forming the shale into nodules. The phosphoric acid prevents loss in mechanical strength of the nodule caused by admixture with the nodule fines.
