At reductant dosage of 25wt.%, the ferronickel particles using straw charcoal formed an accumulated particle cluster. Moreover, some gangue minerals were wrapped tightly and also caught into the powdered ferronickel product when grinding and magnetic separation processes were conducted.

This study aims to model grinding of a Polish ferronickel slag and evaluate the particle size distributions (PSDs) of the products obtained after different grinding times. Then, selected products were alkali activated in order to investigate the effect of particle size on the compressive strength of the produced alkali activated materials (AAMs).
