Hematite Processing by Flotation

2016-4-19  Reagents for Hematite Flotation Reagents are stage added to the conditioners and unless a unit cell is used or a low phosphorus product is to be made, this is the only point of addition. The most common reagents are red oil high in oleic acid content, petroleum sulfonates, a frother and occasionally some mineral oil. Emulsions of the first two are sometimes helpful. Flotation

FLOTATION CHEMISTRY OF HEMATITE/OLEATE SYSTEM

2003-4-2  Currently beneficiation of hematite ores is conducted using either directflotation (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. were among the first to investigate the utility of various collectors in hematiteflotation from quartz. In their extensive study, they concluded that fattyacids and their soapsare superior collectors for hematite flotation

Abstract The aim of this study was to investigate whether commercially available mixtures of the 18-carbon fatty acids could be used as flotation reagents for oxide minerals. These fatty acids are relatively insoluble, but the unsaturated fatty acids are known to have good collecting properties under alkaline pH conditions. Flotation recovery of a sample of hematite using these fatty acids was ...
