The microflotation tests were conducted in a 50 cm3 flotation cell of a XFGII50 laboratory flotation machine (Liu et al., 2010). Taking 5 g single mineral sample (quartz, hematite or magnetite) in the flotation cell with ultrapure water filled. The pulp was stirred for 3 min at a rotating speed of 1992 rpm,
