2016-3-10  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 ).
