The effects of partially replacing amine collectors by a commercial frother in a reverse cationic hematite flotation.

摘要: Abstract Iron ore froth flotation has recently been used to obtain pure minerals due the depletion of high-grade deposits. Amine collectors have often in cationic reverse iron achieve separation with quartz impurities. The main problem associated these is related control frothing properties and high cost amine reagents. In this paper, we report benefits partial replacement a frother hematite. Surface tension batch experimental results indicated for first time that replacing Flotigam EDA, an etheramine collector by more than 10% improved performance both grade recovery It was also noted mild hematite entrainments lower dosages whilst reagents estimation profitability per ton recovered. At higher dosage however, recoveries were observed as result entrainment which led satisfactory terms sink, but showed costs when alone. From results, it concluded partially does improve globally regardless pronounced mainly mineralogy notable amounts locked particles sizes. Finally, would be useful investigate findings alternative on different mineralogical properties.
