    Abstract:

    The achievement for products with high quality has conducting the mining industry to search new routes of technological process. In this context, the concentration of a typical friable itabirite iron ore was evaluated in Brazil with the aim to investigate the potential concentration by magnetic separation and spiral concentrator. Two different samples were tested, one composed by drillcores intervals from geological drillholes and a large outcrop sample. The energy consumption was determined in a bench scale test using Rowland equation to small size mills. The friable ore achieves an outstanding performance for both spiral and magnetic concentration, obtaining a final concentrate of 68,7% and 67,8% iron grade for the drillcores intervals. The energy consumption was considered very low and the evaluation shows that from a sample with 45%>1,0 mm to obtain a grinding product with 8%>1,0 mm, 3,94 Kwh/t were required.
