Hematite ore flotation process. The flotation process is mainly used for the separation of fine and micro-fine weak magnetic hematite ore, including positive flotation process (positive flotation of anionic collector) and reverse flotation process (negative flotation of cationic collector). Commonly used collectors include tallow fatty acid (soap), ...
Hematite Processing by Flotation
Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves.

Flotation of Hematite Using Oleates as Collectors AusIMM. Laboratory scale flotation tests were done on mineral hematite and a specular hematite ore using oleic acid and sodium oleate as collectors The mineral hematite floated strongly in the neutral pH region, with an increased pH range of flotation at higher oleate additions Concentrates with sufficient hematite grade to meet the paint ...
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]

01-10-2017 · Hematite and quartz samples were purchased from GeoDiscovery, Australia. Table 1 and Fig. 2 show the X-ray fluorescence and X-ray diffraction results of these two mineral samples, respectively. As shown, these hematite and quartz samples were highly pure. All mineral samples used in the experiments were crushed, ground and wet-sieved to prepare the flotation feed samples …
Froth Flotation of Iron Ores - Publications
the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

Hematite positive flotation process is a method of using anionic collectors to float iron ore from raw ore. It can achieve discarding tailings under the coarse particles without desliming. Hematite positive flotation process is featured with simple dosage, low processing cost, which is especially suitable for a single hematite.
Effect of particles size range on iron ore flotation
In this way, after sequential conditioning with two reagents, hematite remains clearly hydrophilic and quartz, on the other hand, changes its hydrophilic character to predominantly hydrophobic. Work carried out by Lima (2001) demonstrates the effect of the presence of ultrafine particles (<10um) in the flotation of different iron ore samples.
