Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.
