RECYCLING OF HEMATITE FINE WASTE BY PELLETISATION

2018-5-2  In order to obtain pellets with suitable mechanical and chemical properties, the iron oxide micro fines must be agglomerated as larger pieces. In literature it was studied the use of various types of binders for making pellets. Some of these were applied in the industry. In this work the hematite powder was mixed with solutions of sodium silicate (Na2OxnSiO2, n = 2.4-3.5) or calcium chloride (as solution 30 %) and lime. They are alternative binders to bentonite used for iron ore pelletizing. They ensure the resistance of pellets
