A method for preparing an admixture comprising a particulate material and a fugitive binder for producing green pellets involves: fluidizing and agitating a mass of particulate material with a fluidized bed system, then adding a fugitive binder to the fluidizing and agitating mass of particulate material and blending the binder with the particulate material. The fugitive binder is ammonium bicarbonate, ammonium bicarbonate carbamate, ammonium sesquicarbonate ammonium carbamate, or mixts. thereof. The blended binder and particulate material is aged for a period of more than 48 hrs, and the resulting aged blend is formed by pressing it into a green body.
