Iron Removal of Yaliköy Sand Dunes (10886b65-8653-411d-a43d-c1682f2c69e7)

In this study, it was aimed to produce glass sand with less than 0.15% Fe2O3 for window glass manufacture and glass ware grade with less than 0.05% Fe2O3 from Yalõköy sand dunes having 0.48% Fe2O3. In order to reduce the iron content of the Yalõköy sand dune, magnetic separation, flotation, scrubbing, H2SO4 leaching and drying were used. The optimum iron removal was achieved by H2SO4 baking at 150oC and 8 kg/t acid consumption. In this way, sand concentrate was obtained with 0.04% Fe2O3 and sand recovery 95%.
