efficient depressant in reverse ionic flotation. The results of flotation optimization of hematite ores using matrix of secondorder center rotatable uniform design allowed to define the collector concentration, impeller rotation speed and air flowrate as the main flotation parameters impacting on the iron ore concentrate quality and iron .

Adsorption Of Oleic Acid On Iron Ore. Oleic acid and sodium oleate are the most commonly used collectors for the otation of iron bearing mineralseveral studies on oleatehematite interactions suggested that the oleate adsorption on hematite mainly depends on solution ph 13.Read More
The relevant responses in iron ore reverse cationic flotation are silica grade and iron recovery in the valuable product The flotation performance may be controlled via the dosages of amine collector and starch depressant Low amine dosages are desirable for this reagent is the most expensive.

The lower adsorption of humic acid on these silicate minerals at pH around 10, the normally operating pH value for reverse cationic flotation of iron ores, indicates a good possibility of a more selective depressant for iron oxid CMC had no significant adsorption on these minerals surface but the use of modified CMCs can lead to better resultsRead More

CN1966154A Column type short flow reverse floatation ... The invention relates to a bloodstone posttype shortened reverseflotation selecting method and relative device, wherein it has two systems arranged from high to low, while each one is formed by cyclonestatic micro foam selecting post, slurry mixing cylinder, buffer pool, and concentrate magnetic selector it adds material mine and ...Read More
CiteSeerX - Document Details Isaac Councill, Lee Giles, Pradeep Teregowda The present investigation deals with the recovery of iron values from the screw classifier overflow slimes from an iron ore washing plant by means of reverse cationic flotation as an alternate to direct anionic flotation. Selectivity index, an indicator of separation efficiency, was chosen as the response parameter ...Read More
Phosphoric acid and derivatives eg diphosphonic acid is the most widely used depressant in reverse flotation of phosphate ore in order to depress the valuable mineral apatite while sodium silie and gum arabic are used as depressants for the gangue minerals in direct flotation of the phosphate ores.Read More
1. Introduction. The dependence of magnetic force, gravity and hydrodynamic force on particle size and the entrapment caused by magnetic flocculation severely limit the use of magnetic separation in ultra-fine iron-ore enrichment John, 1974, Arol and Aydogan, 2003.Traditional magnetic separation process was difficult to separate the iron-ore particle less than 100 m Svoboda and Fujita, 2003.Read More
