It has been accepted for inclusion in Retrospective,Effect of microemulsified collector on froth flotation of coal,in the coal froth flotation industry is impractical (Jones et al., 1978). Microemulsions are transparent and thermodynamically stable. Similar to emulsions, they consist of a surfactant (or surfactant and cosurfactant), oil, and water.

This difference could be probably due to the presence of pyrite which might have been depressed at Ph9. These results support the medium-coking characteristic of the coal deposit.

Nigeria is endowed with a large deposit of non-coking coal found in Okaba, Kogi State.

The coal sample was subjected to proximate/particle size analyses and froth flotation mineral processing to reduce the ash and sulphur contents.EFFECT OF KEY VARIABLES ON COAL CLEANING BY FROTH,,rejects and slurries, froth flotation method of coal cleaning has better efficiency and handling. In this method of wet cleaning, froth is made in a flotation cell by bubbling air through water in presence of frothing agents; on addition, pure and light coal adhere to air bubble while the dirtier part sinks to bottom of the cell.
