Abstract :
In this study, the possibility of producing coal with less than 11% ash from tailings
of flotation process was investigated. The effect of six flotation parameters: collector
type, collector consumption, frother type, frother consumption, pulp density and mixing
rate were studied on a sample from a tailing dam. A software based experimental design
approach (DX7) was applied to determine and model effective parameters as well as
flotation optimization through fractional factorial. It was shown that collector type and
flotation machine mixing rate were the most effective parameters on ash content of
concentrate. The results indicated that the production of a desired ash content
concentrate, i.e. < 11% was feasible. It was also shown that at the optimum conditions of
experiment, production of a concentrate with about 10% ash content, and 12% weight
recovery would be possible.
