A Study of Surfactant/Oil Emulsions for Fine Coal Flotation

Abstract

Emulsification studies show that the combination of an oil-soluble surfactant and water-soluble surfactants with oil can produce a stable, water-dispersive emulsion. In particular, with the addition of a nonionic wetting surfactant, emulsified oil is highly dispersed in water with an oil/water droplet size of 5 to 35 um. Photography demonstrates that such droplets can quickly adsorb on and spread at the coal/water interface, significantly improving the flotation response of coal.
