Hematite Processing by Flotation

Hematite Processing by Flotation. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with Sub A Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.

FLOTATION CHEMISTRY OF HEMATITE/OLEATE SYSTEM

flotation (hematite flotation) or indirect flotation (quartz flotation) tech niques depending upon the nature of the available ore bodies. In direct flota tion, iron bearing mineral, mostly hematite, is floated using oleate as collec tor leaving siliceous gangue, usually quartz, in the tailings. Kick et al. [1]

The nature of hematite depression with corn starch in the

The present investigation was initiated to examine the significance and role of polysaccharides in the reverse flotation of iron ore. Since hematite is already hydrophilic at alkaline pH, where reverse flotation is taking place, the role of polysaccharides should be considered with respect to amine adsorption and maintaining hematite in a hydrophilic surface state.

Magnetic seeding depression in flotation of hematite ore

Hematite ore slimes collected from an iron ore mine in Gansu province, China, assaying 43.73% Fe (total) and 24.11% SiO 2 respectively, were used for flotation tests. Its particle size is 96.70% 15 m, and the sample is not suitable for flotation. Pure hematite with an average granularity of 17.11 m was

Flotation Experiments. Flotation recovery of narrow size hematite (53215;20 181;m) particles as a function of pH is given in Figure 10. More than 77% hematite can be recovered in the flotation concentrate around pH 3. Further, flotation recovery decreases with an increase in pH. At around pH 8.5, there is an increase in flotation recovery.

Reverse flotation separation of hematite from quartz

Aug 01, 20190183;32;Selective aggregation of hematite with magnetite enhanced selectivity of flotation separation of fine hematite from quartz. Fine magnetite served as a depressant to flotation of quartz. Magnetic forces dominated aggregation and colloidal forces controlled selectivity of separation.
