Anionic flotation of high-iron phosphate ores—Control of ...

2009-7-1  The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash.The poor flotation of this otherwise high quality ore was attributed to very high concentrations of calcium and sulfate ions (about 1000 and 2000 mg/L, respectively) found in process water,

2005-2-1  Iron ores flotation froths are inhibited by oil content in starch above 2%. Phosphate ores flotation froths are not affected by oil contents as high as 4%. An explanation for this difference in behaviour may be the fact that the frothing agent in phosphate flotation is the ionised fatty acids soap species.

Starch exhibits excellent adsorption performance on hematite at a slightly alkaline pH. The flotation of hematite is depressed with dodecylamine acting as a collector, however, the flotation of quartz is minimally influenced. Thus, starch is commonly used to depress the flotation of iron minerals in the reverse flotation of hematite , .
