Abstract
The effects of oxidation on flotation recovery of oxidation at 20 degr ees C, 50 degrees C and 100 degrees C for periods up to 100 hours were investigated using an alcohol type frother. The recovery of the float ed coal decreased from 95 percent to 24 percent after oxidation. As a result of measurements with a low-ash bituminous coal, flotation is su ggested as a method of investigating the initial stages of oxidation o f coal particles.
