Effects of Non-Ionic Surfactant on the Deep Temperature Flotation Agents of Hematite

Abstract

This investigation involves the effects of non-ionic surfactant materials on the industrial sodium oleate, sodium naphthenate and their mixtures at different temperatures by the surface tension methods. The effects on the critical micelle concentration (CMC) of sodium oleate were assessed by the Toween 80(T-80) presence, polyethylene glycol, polyether and other non-ionic surfactant. T-80 was proved more effective than other non-surfactant in increasing the sodium oleate CMC at same concentration. Using the optimal composition of sodium fatty acid and the surfactant can reduce the temperature of separation hematite from 43°C to 23°C, achieve the purpose of low carbon and energy saving.
