Silica Removal. Lower grade deposits have significant silica content and this restricts the saleability of the beneficiated iron ore product. DEC Flotation columns have been used and produced very good results in reducing the silica content. Typically, silica can be reduced from 5 7.5% to 2 3% while the iron ore grade is increased from 58 61.5%
