Abstract
A method for agglomerating mineral fines for example iron ore fines, as described. The method comprises the steps of pelletizing a mixture comprising mineral fines and raw starch, treating the pellets so as substantially to gelatinize the starch and then drying the pellets or allowing them to dry. The process, which may be conducted without necessity to fire the pellets, yields adequate cold compressive strength at relatively low cost.
