As there are two kinds of silica, the floated silica will be referred to along the paper as the quartz silica. The SEM examination ( Fig. 1 ) has shown that quartz silica particles are liberated. There are liberated gibbsite particles, although most of them presented fine titanium and iron bearing minerals incrustations or coatings.

In contrast, in silica bearing iron ore, the quartz particles are coarser in size and less prone to be coated on iron minerals. In fact there are a number of investigations based on reverse flotation techniques for the separation of quartz particles from hematite fines ( Montes-Sotomayor et al., 1998, Uwadiale, 1992, Yuhua and Jianwei, 2005 ).
