Using Polyoxyethylene Reduction the Flotation Temperature of Fatty Acid
The separation of quartz from hematite adding the polyoxyethylene ether to the fatty acid has been investigated. The main factors affecting flotation temperature were found to be constitutes of collector and surfactants. The results indicate that the temperature of fatty acid anion reverse flotation of iron ore could be reduced to 22 from 45 . It can achieve purposes of saving energy and lowering carbon let.
