Iron Ore Producer Realizes Immediate Savings and Operational Benefits

HANOVER, MA – Sturtevant, Inc. today announced the sale of three 26-foot Whirlwind® Air Classifiers to Fortescue Metals Group Ltd (FMG) in Australia as part of the Iron Bridge Project. The high-throughput operation will remove beneficiated Magnetite fines at 120-mesh, 200-mesh and 325-mesh and increase iron concentration.  Thereby, the refined and enriched iron ore will be sold at higher prices.IMG_1426-cropped

Fortescue Metals Group Ltd chose the Whirlwind® Air Classifier because of its dry air classification process. Wet washing requires expensive capital equipment, high energy output and a high volume of water. Dry separation requires less capital investment, less water and energy costs and provides exponential savings over wet washing.  Sam Rajkovich, Sturtevant’s Director of Sales & Marketing said, “Dry air classification saves our customer money on the initial capital investment and allows them to refine and improve the quality of their iron more economically than any other method of particle separation.”

Another crucial factor for Fortescue Metals Group Ltd’s choice was that the Whirlwind® Air Classifier was efficient even at high moisture contents. The Whirlwind® offered the most flexibility during variable process conditions including weather, temperature, and humidity changes.
