The flotation behavior of quartz, hematite and magnetite under α-BLA reverse flotation system were investigated and the separation mechanism of quartz-irons was studied by contact angle, zeta-potential and infrared spectroscopy. The results showed that the optimum flotation pH was 11.5 for quartz, 6.45 for hematite and 6.97 for magnetite.
Recently, Tohry et al. (2019) indicated that sodium co-silicate (SCS) as a modified SS could be considered for the industrial RAF separation of hematite from fluorapatite.[16] However, SCS interactions on the sur-face of hematite, quartz, and fluorapatite have not been investigated yet.

From a mineralogical point of view, hematite is preferred over magnetite, as it is easier to reduce -6 m3/kg, hematite: 0.6–2.16×10-6 m3/kg; Xiong et al., 2015). Hematite is very often associated with hydrohematite and goethite, which have lower magnetic susceptibility than hematite
Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a ...
The results indicate that such a process is a feasible and efficient method for iron and phosphorus separation of high phosphorus oolitic hematite. The recovery of metallic iron and dephosphorisation rate is relatively low without additives but is significantly improved by appropriate CaO …
