Numerous industries including detergent, food, mining, pharmaceutical and powder metallurgy have commonly encounted flow issues due to undesirable transform of readily free flowing solids to a coherent solid. In the present study, the flow properties of LD iron ore were studied in the presence of polymer flow aids such as superabsorbent polymers (SAP). The effect of moisture, clay content, SAP dosage and its retention time on flow properties of wet sticky iron ore were explored. Flow properties such as Hausner ratio (HR), Carr index (CR), flow function index, effective angle of internal friction and cohesion were measured using Powder flow tester. Results indicated that LD iron ore exhibited free flow at dry condition and very poor flow at 8%, 10% and 12% moistures. In the presence of SAP, LD iron ore has changed its flow behaviour to easy flow regime due to their high affinity for moisture absorption. Optimum dosages of SAP were found to be 1200 ppm, 1400 ppm and 1800 ppm for these wet sticky LD iron ores of 8%, 10% and 12% moistures respectively. Experimental data concluded that SAP dosage was based on moisture content, clay content and % of fines fraction in the ore. (C) 2020 Elsevier B.V. All rights reserved.
